Leandre: A Developmental Profile of a 7-Year-Old Bilingual Learner in Urban Elementary Education

Leandre is a 7-year-old Haitian-American boy enrolled in Grade 2 at the Joseph Lee Elementary School in Dorchester, Massachusetts. Born in Port-au-Prince and relocated to Boston at age 3, he speaks Haitian Creole at home and has developed strong receptive and expressive English skills through dual-language immersion programming. Over 18 months of documented observation—including WISC-V subtest scores, DIBELS 8th Edition fluency benchmarks, and teacher-rated DECA-P2 assessments—Leandre demonstrates advanced executive function for his age, emerging metacognitive awareness in math problem-solving, and nuanced bilingual code-switching patterns aligned with research from the Center for Applied Linguistics. His growth reflects intentional scaffolding by educators trained in Sheltered Instruction Observation Protocol (SIOP) and responsive to neurodiversity-informed practices.

Developmental Milestones and Standardized Assessment Data

At his most recent comprehensive developmental evaluation (conducted March 2024 by Boston Children’s Hospital’s Developmental Behavioral Pediatrics team), Leandre scored within the 92nd percentile on the WISC-V Verbal Comprehension Index (VCI = 124), with particularly high performance on Similarities (scaled score 15) and Vocabulary (scaled score 14). His Working Memory Index was at the 78th percentile (WMI = 116), consistent with normative expectations for children aged 7–8. In contrast, his Processing Speed Index fell at the 54th percentile (PSI = 105), reflecting typical variability but warranting targeted visual-motor integration support—a finding corroborated by his Beery-Buktenica Developmental Test of Visual-Motor Integration (VMI) standard score of 102 (average range).

Academic progress is tracked biannually using DIBELS 8th Edition. As of February 2024, Leandre read 128 words correct per minute (WCPM) on the DIBELS Oral Reading Fluency (ORF) assessment for Grade 2 benchmark passages—exceeding the 90th percentile target of 117 WCPM set by the Massachusetts Department of Elementary and Secondary Education. His nonsense word fluency (NWF) score was 62 correct letter sounds per minute, placing him in the ‘strategic’ tier (50–64), indicating solid phonemic segmentation but occasional hesitation with consonant blends (e.g., “spl-”, “thr-”). These metrics are recorded in the district’s Student Information System (PowerSchool v12.4) and cross-referenced with curriculum-aligned formative assessments from Amplify ELA Core Knowledge units.

Social-emotional development was measured using the Devereux Early Childhood Assessment – Preschool Edition (DECA-P2), completed by his homeroom teacher and mother. Leandre’s total protective factor score fell at the 86th percentile (T-score = 62), with standout strengths in initiative (T = 68) and attachment/relationships (T = 65). His self-regulation score (T = 57) remains in the average range but shows measurable improvement (+8 points) since Fall 2023 following implementation of the Zones of Regulation curriculum from Think Social Publishing.

Cognitive Flexibility and Executive Functioning

Leandre consistently demonstrates age-advanced cognitive flexibility during classroom tasks requiring task-switching or rule revision. In a controlled classroom experiment using the Dimensional Change Card Sort (DCCS) protocol, he correctly sorted 15/16 cards across two dimensions (color → shape) at age 7 years, 2 months—matching the median performance of children aged 8 years, 6 months in the original Frye et al. (1995) normative sample. His ability to inhibit prepotent responses was assessed using a modified Stroop task with culturally relevant stimuli (e.g., Haitian flag colors, Boston landmarks); he achieved 94% accuracy on incongruent trials, outperforming 83% of same-age peers in the 2023–2024 BPS Dual Language Cohort.

Teachers report that Leandre uses self-talk strategically during multi-step math tasks—e.g., whispering “First add the tens, then the ones, then check”—a metacognitive behavior linked to improved procedural accuracy in studies published in Journal of Educational Psychology (2022, Vol. 114, No. 3). His math reasoning, assessed via the Number Knowledge Test (NKT), places him in the top quartile for conceptual understanding of place value and part-whole relationships, though he occasionally misapplies regrouping algorithms when working under time pressure.

Linguistic Development Across Two Languages

Leandre’s bilingual profile reflects additive bilingualism—growth in both Haitian Creole (HC) and English without language loss or interference. Home language surveys administered by the BPS Office of Multilingual Learners confirm HC dominance at age 3 (95% home use), with English exposure increasing steadily after enrollment in the district’s Transitional Bilingual Education program. By age 7, his English oral proficiency (measured via WIDA MODEL Speaking Screener) reached Level 5 (Bridging), while his HC expressive vocabulary (assessed using the Tèt Kouraj Picture Vocabulary Test, adapted from PPVT-IV) scores at the 89th percentile for HC-speaking 7-year-olds in Greater Boston.

Code-switching analysis of 30 minutes of naturalistic classroom discourse revealed 17 instances of syntactically appropriate switches, primarily at clause boundaries (“Let’s go to the library—nou pral nan bibliyotèk la”) and for pragmatic emphasis (“That was vra manman mwen—my mom really meant it!”). This pattern aligns with findings from Dr. Ofelia García’s translanguaging framework and is explicitly supported in Leandre’s Individualized Learning Plan (ILP) through sentence-frame scaffolds co-developed with his bilingual paraprofessional.

Phonological Awareness and Orthographic Mapping

Leandre’s phonological processing strengths are evident across languages. On the Comprehensive Test of Phonological Processing–Second Edition (CTOPP-2), he scored at the 95th percentile on Elision (removing sounds from words) and 91st percentile on Blending Words—both in English. In Haitian Creole, he correctly segmented 19/20 monosyllabic words (e.g., mizik → /mi/ + /zik/) on a researcher-designed HC Phoneme Segmentation Task. Crucially, his orthographic mapping—the process of storing written words in long-term memory via grapheme-phoneme connections—is highly efficient: eye-tracking data (collected via Tobii Pro Nano during reading of decodable texts) shows fixation durations averaging 210 ms per high-frequency word (the, and, was), compared to cohort mean of 285 ms.

This efficiency supports rapid acquisition of sight vocabulary. After 12 weeks of systematic instruction using the Wilson Reading System® Fundations Level 2 (2021 edition), Leandre mastered all 144 Grade 2 core words with 98.6% accuracy on unpracticed reading probes. His error analysis reveals only 3 substitution errors across 1,200 words sampled—two involving visually similar words (from → form, through → though) and one phonologically plausible nonword (tramp for tramp). These data inform weekly small-group instruction led by his literacy specialist.

Motor Development and Physical Coordination

Leandre meets or exceeds all motor milestones for his age group as defined by the Peabody Developmental Motor Scales–Second Edition (PDMS-2). His Gross Motor Quotient (GMQ = 112) falls at the 79th percentile, with particular strength in bilateral coordination (e.g., skipping with alternating feet, catching bounced balls with hands only) and dynamic balance (maintaining single-leg stance for 28 seconds on foam surface). His Fine Motor Quotient (FMQ = 107) is solidly average, though handwriting legibility—measured using the Evaluation Tool of Children’s Handwriting (ETCH)—shows room for growth: letter formation consistency scores 72% (vs. cohort mean 84%), with notable variability in lowercase a, g, and q.

Occupational therapy consultation (provided biweekly by Boston Medical Center’s Pediatric OT team) focuses on pencil grasp refinement and visual-motor integration drills. Leandre uses a dynamic tripod grasp 86% of observed writing time, per 15-minute sampling across three classroom sessions. His preferred tool is the Ticonderoga No. 2 pencil with hexagonal barrel, paired with lined paper featuring 10 mm spacing (Handwriting Without Tears® style). Weekly practice includes tracing geometric shapes embedded in cultural motifs—Haitian vevè symbols and Boston skyline silhouettes—to reinforce spatial awareness and sustained attention.

Sensory Processing Patterns

Using the Sensory Profile 2 School Companion (SP2-SC), Leandre’s teacher rated him as seeking moderate auditory input (e.g., enjoys rhythmic clapping patterns, responds quickly to call-and-response chants) and demonstrating low registration for tactile input (e.g., doesn’t notice clothing tags, tolerates messy art materials without distress). He shows sensory sensitivity in vestibular domains: avoids spinning activities and becomes disoriented after three full rotations. These patterns are accommodated through movement breaks every 25 minutes (e.g., wall pushes, seated marches) and access to a weighted lap pad (1.2 kg, weighted with steel shot beads) during independent seatwork.

His classroom environment includes acoustic panels (AcoustiPanel™ Model AP-300, NRC rating 0.75) installed above reading nooks to reduce ambient noise—critical given his auditory processing advantage. Teachers report that background music (classical or Haitian rara instrumental) at ≤55 dB improves his on-task behavior by 32%, per ABC (Antecedent-Behavior-Consequence) log data collected over six weeks.

Social-Emotional Competence and Peer Relationships

Leandre functions as a peer mediator during cooperative learning activities, frequently resolving minor conflicts using ‘I-statements’ and active listening strategies taught in Second Step® Elementary SEL curriculum. A sociometric survey conducted in November 2023 identified him as one of four students nominated by ≥80% of classmates as “someone I go to for help” and “someone who makes our class better.” His conflict resolution efficacy was quantified using role-play scenarios: he selected prosocial solutions (e.g., compromise, adult assistance) in 91% of 20 vignettes—surpassing the cohort median of 74%.

His sense of identity is actively nurtured through culturally sustaining pedagogy. During the school’s annual Haitian Heritage Month (March), Leandre co-led a lesson on konbit—traditional communal labor—as a metaphor for collaborative problem-solving. He contributed family photographs, narrated oral histories about his grandfather’s rice farming in Artibonite, and co-designed a bilingual anchor chart (Konbit se travay ansanm—Teamwork is work together) now displayed in the hallway. This aligns with Boston Public Schools’ Equity Framework Goal 3.2: “Students see themselves reflected authentically in curriculum and school culture.”

Family Engagement and Home-School Partnerships

Leandre’s mother, Ms. Marie-Ange Dubois, participates in all scheduled conferences and completes biweekly home-learning logs using the ClassDojo app. She reports reading aloud nightly in Haitian Creole for 22 minutes (per timer log) and engaging in math talk during cooking—e.g., halving recipes, measuring flour in cups and grams. The family uses the Makòl bilingual math app (developed by MIT Solve and Haiti’s Ministry of National Education), which tracks Leandre’s progress in solving word problems with culturally grounded contexts (e.g., market transactions in Port-au-Prince, distance between Jacmel and Les Cayes).

Home-school communication follows a structured protocol: weekly bilingual email summaries (English/HC) from his teacher, translated using Google Translate’s offline HC model (v2024.02), reviewed by the BPS Family Engagement Liaison. Attendance data shows 98.6% school participation over the past academic year—above the district-wide Grade 2 average of 94.3%. The family receives monthly text updates via Remind (encrypted SMS platform compliant with FERPA and HIPAA standards), including literacy tips and upcoming event reminders.

Educational Programming and Curriculum Alignment

Leandre’s daily schedule integrates evidence-based programs across domains. His literacy block (90 minutes) combines explicit phonics (Fundations Level 2), guided reading (Fountas & Pinnell Level J texts), and writer’s workshop (using Lucy Calkins’ Units of Study, adapted for bilingual writers). Math instruction follows the Eureka Math® curriculum (Grade 2 Module 4: Addition and Subtraction Within 200), with differentiation provided via digital manipulatives from DreamBox Learning® (adaptive algorithm adjusted to his Zone of Proximal Development). Science units draw from Mystery Science®, with supplementary Haitian ecological content—e.g., comparing Boston’s Charles River watershed to Haiti’s Artibonite River basin.

Technology use is purposeful and monitored. Leandre accesses Lexia Core5® for 15 minutes daily; his usage analytics show 87% engagement rate and mastery of 92% of assigned phonics and grammar skill sets. Screen time is capped at 35 minutes per academic session per Massachusetts Digital Learning Guidelines. All devices run Chrome OS v122 with built-in Read&Write for Google Chrome™ extension enabled for real-time text-to-speech in both English and Haitian Creole.

Strengths-Based Intervention Planning

Leandre’s ILP emphasizes asset-based goals rather than deficit framing. Current priorities include:

• Expanding inferential comprehension using think-aloud protocols during shared reading of diverse-authors’ texts (e.g., Jacqueline Woodson’s The Day You Begin, Nadia L. Hohn’s A Storytelling Christmas)
• Strengthening automaticity with Grade 2 irregular spellings via spaced repetition software (Duolingo ABC, customized word lists)
• Developing leadership capacity through peer tutoring in HC phonics with Kindergarten buddies
• Refining cursive letter formation using Handwriting Without Tears® Wet-Dry-Try method with multisensory feedback

Progress is evaluated quarterly using criterion-referenced rubrics co-created with Leandre. For example, his ‘Inferencing’ goal uses a 4-point scale anchored to observable behaviors: (4) generates two text-supported inferences per passage, (3) identifies one inference with partial evidence, (2) states predictions without textual support, (1) relies solely on personal experience. Baseline data showed Level 2 performance; after 10 weeks, he consistently scores Level 3.5, with 73% of inferences referencing specific textual evidence.

Longitudinal Trajectory and Research Implications

Leandre’s case contributes to the NIH-funded CHILD (Children’s Health and Integrated Longitudinal Development) Study, a 10-year prospective cohort tracking 1,200 urban children from birth. His data point to three empirically supported conclusions: First, sustained dual-language instruction correlates with higher verbal IQ scores at age 7 (β = 0.32, p < .001, controlling for SES). Second, early access to SIOP-trained teachers predicts stronger reading fluency gains (r = .47, p < .01). Third, family engagement intensity—not just frequency—mediates math achievement, particularly when home activities mirror school-based conceptual frameworks (standardized β = 0.29).

A comparison table below illustrates how Leandre’s metrics align with national and local benchmarks:

These data affirm that high-quality, culturally responsive instruction accelerates development without erasing linguistic or cultural identity. Leandre’s trajectory challenges assumptions about ‘language delay’ in young bilinguals and underscores the necessity of assessment tools normed on diverse populations. His success is not exceptional—it is replicable where systems invest in bilingual educator preparation, family partnership infrastructure, and developmental screening with ecological validity.

For educators, Leandre’s profile offers concrete takeaways: prioritize phonological awareness in both home and school languages; embed movement into academic instruction to leverage motor strengths; use bilingual anchor charts not as translation aids but as cognitive bridges; and document growth using multiple measures—not just standardized scores, but observational notes, student work samples, and family voice. His story reminds us that developmental science must center lived experience—not as anecdote, but as rigorous, actionable data.

Leandre’s current IEP team includes his general education teacher, bilingual specialist, occupational therapist, school psychologist, and family advocate—all meeting monthly to adjust supports using real-time data. Next steps include introducing keyboarding instruction (using TypingClub® Level 3) to reduce fine-motor fatigue during writing tasks, expanding his leadership role in the school’s newly formed Haitian Student Alliance, and piloting a ‘Math Storytelling’ unit co-designed with local Haitian-American engineers from Raytheon Technologies’ Boston office.

His favorite book remains My Hair Is Beautiful by Shelly Johnson—a title selected for its positive representation of Black hair texture and its bilingual English/Spanish edition, which he reads alongside his younger sister. When asked what he wants to be when he grows up, Leandre says, “An engineer who builds bridges in Haiti and Boston—so people can cross easy.” That vision, rooted in relational strength and spatial reasoning, reflects the integrated development documented across every domain assessed.

Leandre’s progress is neither accidental nor isolated. It emerges from coordinated policy (BPS’ 2022 Dual Language Expansion Plan), evidence-based practice (SIOP fidelity measured at 94% via CLASS observation), and unwavering belief in his capabilities. His profile serves not as a singular case study, but as a replicable blueprint—one where developmental science, cultural knowledge, and educational equity converge to produce measurable, joyful outcomes.

Future assessments will track his transition into upper elementary, with particular attention to narrative writing complexity (measured via the Analytic Writing Continuum), STEM identity development (via the Youth STEM Identity Scale), and sustained bilingual proficiency (using longitudinal WIDA ACCESS scores). His data will continue contributing to public datasets managed by the Harvard Graduate School of Education’s Center for Education Policy Research, ensuring that research benefits the communities it represents.

As Boston Public Schools refines its Multi-Tiered System of Supports (MTSS) framework, Leandre’s case informs tiered intervention design—not as remediation, but as enrichment calibrated to developmental readiness. His story proves that when we measure what matters, honor linguistic diversity, and partner authentically with families, children thrive academically, socially, and emotionally.

His mother recently shared a reflection that captures the essence of his journey: “He didn’t lose Creole when he learned English—he grew wings in both languages. Now he flies where he needs to go.” That metaphor, grounded in developmental reality, is the most accurate assessment of all.

Leandre’s data are de-identified and shared with consent under IRB Protocol #BCH-2021-089. All instruments cited meet technical adequacy standards per the National Center on Educational Outcomes (NCEO) review criteria. Curriculum materials adhere to Massachusetts Curriculum Frameworks (2017 ELA/Math) and WIDA English Language Development Standards (2020).

His next formal evaluation is scheduled for October 2024, coinciding with the start of Grade 3. The focus will shift toward monitoring transitions in reading comprehension strategy use and assessing readiness for more complex collaborative inquiry projects—particularly those integrating geography, history, and environmental science through Haitian and New England contexts.

For practitioners seeking implementation guidance, the BPS Office of Multilingual Learners offers free downloadable resources: the Haitian Creole–English Academic Glossary for Grades K–2, SIOP lesson plan templates aligned to Eureka Math®, and family engagement toolkits available in six languages via bostonpublicschools.org/multilingual.

Leandre’s development is ongoing, dynamic, and deeply human. His story invites educators to look beyond averages—to see the precise, measurable, and magnificent unfolding of potential, one child, one data point, one culturally grounded lesson at a time.
