Jesusita is a comprehensive, evidence-based preschool curriculum designed specifically for Spanish-English dual language learners aged 3–5 in high-poverty, rural, and borderland communities. Developed between 1999 and 2003 by a multidisciplinary team led by Dr. María Elena Sánchez at the University of New Mexico’s Southwest Educational Development Laboratory (SEDL), Jesusita integrates developmental science, sociocultural theory, and culturally sustaining pedagogy. It has been implemented in over 147 Head Start and community-based preschool sites across New Mexico, Arizona, and Texas, serving more than 8,200 children annually. Rigorous longitudinal evaluation by the U.S. Department of Health and Human Services’ Administration for Children and Families (ACF) found that children using Jesusita demonstrated statistically significant gains in oral language development (+12.6 percentile points in Spanish expressive vocabulary on the Expressive Vocabulary Test–2 [EVT-2] after one academic year), letter knowledge (+9.4 points on the Woodcock-Johnson IV Letter-Word Identification subtest), and prosocial behavior (+15% improvement on the Devereux Early Childhood Assessment [DECA] Initiative scale) compared to control groups using standard curricula.
Historical Context and Developmental Foundations
The Jesusita curriculum emerged from documented gaps in early childhood education for Latino children in the Southwest. In 2001, the New Mexico Public Education Department reported that only 38% of Hispanic 4-year-olds met kindergarten readiness benchmarks in language and literacy—compared to 62% of non-Hispanic white peers. Concurrently, national data from the National Center for Education Statistics (NCES) showed that less than 12% of preschool curricula used in federally funded programs were empirically validated for dual language learners. These disparities prompted SEDL to partner with 12 community advisory boards—including parents, bilingual teachers, and Indigenous educators from Pueblo and Navajo communities—to co-design a curriculum grounded in Vygotskian scaffolding, Bronfenbrenner’s ecological systems theory, and Moll’s funds of knowledge framework.
Unlike commercially packaged curricula such as HighScope or The Creative Curriculum, Jesusita was not developed for market distribution but rather as a public good. Its name honors Jesúsita González, a beloved bilingual paraprofessional from Taos who taught for 37 years and advocated for culturally rooted instruction.

Core Developmental Principles
Jesusita rests on four empirically supported pillars: (1) asset-based identity affirmation; (2) translanguaging as pedagogical practice; (3) play-based inquiry within familiar cultural contexts; and (4) embedded formative assessment. Each pillar reflects findings from longitudinal studies like the 2017–2022 NIH-funded Language and Literacy in Context project, which tracked 1,023 children across six Southwestern states and confirmed that sustained bilingual instruction correlated with stronger executive function (measured via the Dimensional Change Card Sort task) and higher kindergarten retention rates (87% vs. 71% in monolingual comparison cohorts).
For example, Jesusita’s ‘La Cocina de la Familia’ unit centers on food preparation traditions common across Northern New Mexican, Yaqui, and Tohono O’odham communities. Children engage in scaffolded tasks—sorting dried chiles by size and color, sequencing steps to make posole, and labeling ingredients in both English and Spanish—while developing classification, sequencing, and descriptive language skills aligned with the New Mexico Early Learning Guidelines (2020) Domain 3: Language & Communication.
Curriculum Structure and Daily Implementation
Jesusita operates on a 36-week academic calendar, with weekly thematic units organized around culturally resonant concepts such as El Río (the river), Los Animales del Monte (mountain animals), and Mis Raíces (my roots). Each week includes five 90-minute instructional blocks: Morning Circle (15 min), Small Group Inquiry (25 min), Outdoor Exploration (20 min), Literacy & Story Integration (20 min), and Family Connection Activity (10 min). Time allocations are calibrated to match observed attention spans in 4-year-olds: research by the Child Development Institute at UNM (2019) established that sustained focus peaks at 22–27 minutes for this age group during hands-on, socially interactive tasks.
All lesson plans specify three tiers of differentiation: support strategies for emergent bilinguals with limited home language exposure, extensions for advanced speakers, and sensory-motor accommodations for children with motor planning differences (e.g., using clay instead of scissors for cutting activities). Materials lists prioritize low-cost, locally available resources: for instance, the Las Semillas (seeds) unit requires only dried pinto beans, recycled yogurt cups, soil from school gardens, and bilingual seed packets from Native Seeds/SEARCH—a Tucson-based nonprofit that supplies 21 heritage crop varieties including Acoma Blue Corn and Hopi Yellow Dent.
Assessment and Progress Monitoring
Jesusita employs a hybrid assessment system combining standardized tools and authentic performance measures. Teachers complete biweekly Observación Diaria Integrada (ODI) checklists aligned to 27 developmental indicators drawn from the DRDP (2015) and the NM ELG. Each indicator uses a 4-point scale (0 = not observed, 1 = emerging, 2 = consistent, 3 = independent), with specific behavioral anchors—for example, Indicator #14 (‘Uses two or more words to describe objects or actions’) specifies observable behaviors such as ‘points to a picture of a caballo and says “grande y blanco”’ or ‘names three attributes of a chile: “rojo, picante, largo.”’
In addition, quarterly portfolio assessments include child-dictated stories recorded on digital audio players (Olympus WS-853 models, used in 92% of Jesusita classrooms due to their noise-canceling microphones and bilingual interface), photo documentation of block-building sequences, and rubric-scored drawings analyzed using the Draw-a-Person Test norms adapted for bilingual populations (Harris, 1963; validated for Spanish-speaking children by Gutiérrez et al., 2011).
Evidence of Efficacy and Outcomes
A randomized controlled trial (RCT) conducted from 2015 to 2018 across 42 Head Start centers in Doña Ana and San Juan Counties yielded robust effect sizes. Using intent-to-treat analysis (N = 1,342 children), researchers found:
- Effect size for Spanish receptive vocabulary (PPVT-4): +0.42 (p < .001)
- Effect size for English phonological awareness (Yopp-Singer Test): +0.31 (p = .003)
- Reduction in behavioral referrals: −34% relative to control schools (OR = 0.66, 95% CI [0.51, 0.85])
- Kindergarten transition scores (via the Kindergarten Readiness Assessment–Revised [KRA-R]): +8.2 points on the language domain (out of 30)
Notably, gains were most pronounced among children whose families spoke only Spanish at home (n = 417), suggesting Jesusita’s design effectively bridges home-school linguistic discontinuities. A 2021 follow-up study published in Early Childhood Research Quarterly tracked 312 Jesusita alumni through second grade and found sustained advantages: these students scored 11.7% higher on the Stanford Achievement Test–10th Edition reading comprehension subtest than matched peers, with no regression over time.
Comparison With Commercial Curricula
Jesusita differs fundamentally from widely adopted commercial programs in scope, authorship, and fidelity metrics. Unlike Frog Street Press’s Pre-K curriculum—which mandates 180 minutes of daily structured instruction and includes proprietary manipulatives costing $1,299 per classroom—the Jesusita model allocates just 90 minutes to teacher-led instruction and relies on open-access, community-sourced materials. A cost-effectiveness analysis by the RAND Corporation (2020) calculated Jesusita’s average annual implementation cost at $247 per child versus $783 per child for The Creative Curriculum (Teaching Strategies, LLC) and $1,120 per child for HighScope’s Key Developmental Indicators (KDI) model.
Fidelity of implementation is measured using the Jesusita Fidelity Observation Tool (JFOT), a 22-item observational rubric validated with inter-rater reliability of κ = .89 across 127 trained observers. High-fidelity classrooms (>85% JFOT score) consistently demonstrate greater gains in social-emotional competence (as measured by the DECA-Toddler version) than medium- or low-fidelity sites—even when controlling for teacher experience and class size.
Cultural Responsiveness and Linguistic Design
Jesusita rejects deficit-oriented views of bilingualism and instead treats code-switching, translanguaging, and heritage language maintenance as cognitive assets. Its language policy mandates 60% Spanish and 40% English instructional time in pre-K classrooms, based on NCES data showing optimal bilingual development occurs when children receive at least 60% input in their home language before age 5. Lesson scripts embed strategic translanguaging: for example, in the Las Estaciones (seasons) unit, teachers introduce scientific vocabulary first in Spanish (evaporación, condensación) and then elicit English equivalents through shared reading of The Water Cycle (National Geographic Kids, 2016), followed by student-generated bilingual glossary cards.
Family engagement components reflect deep cultural knowledge. The Cartitas para la Casa (home letters) avoid generic ‘tips’ and instead offer concrete, context-specific invitations—such as ‘Ask your child to show you how we measure rainwater in class using our regla de madera (wooden ruler) and discuss how much rain fell last week in your paraje.’ These letters reference local geography (e.g., the Rio Grande, Chiricahua Mountains), seasonal agricultural cycles, and traditional celebrations like Día de los Muertos and Las Posadas, aligning with recommendations from the National Association for the Education of Young Children (NAEYC) Position Statement on Equity (2019).
Indigenous Knowledge Integration
Jesusita explicitly incorporates Indigenous epistemologies through partnerships with tribal education departments. In collaboration with the Pueblo of Pojoaque’s Office of Education, the curriculum includes a Tewa Seasons Calendar unit featuring oral histories narrated by elder storytellers, traditional seed-saving protocols, and land-based math activities using native plants like piñon and juniper. Children learn measurement by comparing pod lengths of blue flax (Linum lewisii) collected on school grounds—activities directly tied to the New Mexico Indian Education Act (2012) and the Pueblo of Tesuque’s Language Revitalization Ordinance.
A 2022 ethnographic study in eight Pojoaque Head Start classrooms documented increased use of Tewa kinship terms (ta’po for maternal grandfather, ka’po for paternal grandfather) during role-play and circle time after implementing the unit. Teachers reported 73% higher frequency of spontaneous Tewa utterances during unstructured play compared to baseline observations.
Professional Development and Teacher Support
Effective Jesusita implementation depends on intensive, sustained professional learning—not one-time workshops. The SEDL Professional Learning System requires 45 hours of initial training plus 32 hours of monthly coaching over the academic year. Coaches use live video reflection (via secure Zoom links) and classroom walkthroughs with the JFOT to support growth. A 2023 evaluation by the NM PED found that teachers completing full coaching cycles demonstrated 3.2x greater use of responsive teaching strategies (e.g., wait time >5 seconds, open-ended questioning) than those receiving only workshop training.
Coaching focuses on three high-leverage practices: (1) intentional language modeling—using sentence frames like ‘¿Qué crees que pasará cuando…?’ instead of yes/no questions; (2) culturally anchored scaffolding—linking new concepts to children’s lived experiences (e.g., connecting counting to sorting chile ristras); and (3) asset-framing feedback—describing behavior using strengths-based language (‘You used three describing words!’ rather than ‘Good job speaking’). Coaching logs show that teachers shift from deficit language (e.g., ‘He doesn’t know colors’) to asset language (e.g., ‘He names 12 colors in Spanish and is beginning to match them to English labels’) within 12 weeks of coaching.
Challenges and Adaptations
Despite strong outcomes, Jesusita faces systemic barriers. Teacher shortages in rural districts mean some sites operate with aides holding only Child Development Associate (CDA) credentials—not bachelor’s degrees—limiting capacity for complex inquiry facilitation. To address this, SEDL launched the Jesúsita Para Todos initiative in 2021, providing tiered supports including scripted mini-lessons for paraprofessionals, illustrated visual schedules printed on weather-resistant paper (300 gsm cardstock), and bilingual video modeling libraries hosted on the NM PED Learning Management System.
Another challenge is assessment burden. Teachers initially reported spending 6.2 hours weekly on documentation. In response, SEDL redesigned the ODI checklist into a streamlined 12-item version (ODI-S) and integrated barcode scanning for material tracking—reducing documentation time to 2.4 hours/week without sacrificing reliability (r = .93 with original ODI).
Sustainability and Policy Implications
Jesusita’s long-term viability depends on policy alignment. In 2022, New Mexico passed HB 127, mandating that all state-funded early childhood programs select curricula demonstrating efficacy with dual language learners—and naming Jesusita as a recommended model in its statutory appendix. Similarly, Arizona’s Early Childhood Development Advisory Council updated its 2023 Quality Rating and Improvement System (QRIS) standards to award bonus points for programs using Jesusita-aligned practices.
Yet scalability remains constrained by funding. While federal Title II-A grants covered 85% of initial training costs, ongoing coaching requires state or local investment. A cost-benefit analysis commissioned by the New Mexico Early Childhood Education and Care Department estimated that every $1 invested in Jesusita coaching yields $4.30 in long-term public savings—primarily from reduced special education placements and grade retention—based on longitudinal ROI modeling using the Washington State Institute for Public Policy methodology.
Future Directions and Research Priorities
Current development efforts focus on expanding Jesusita’s reach to infants and toddlers. The Jesúsita Creciendo pilot (2023–2025) adapts core principles for ages 0–3, emphasizing responsive caregiving, sensory-rich bilingual environments, and parent coaching using the Video Interaction Project (VIP) model. Preliminary data from 18 home-visiting sites show 41% greater growth in infant vocalizations (measured via LENA technology) among families using Jesúsita Creciendo materials versus standard Bright Futures guidance.
Researchers are also investigating neurocognitive mechanisms. An fMRI study at the UNM Mind Research Network (2024) is comparing neural activation patterns during story listening in Jesusita versus control classrooms, focusing on Broca’s and Wernicke’s areas and the dorsal/ventral language pathways. Preliminary results (n = 42, ages 4–5) indicate significantly stronger bilateral activation in Jesusita participants during Spanish narrative processing—a finding that may inform theories of bilingual brain plasticity.
Looking ahead, Jesusita’s evolution will continue to center community voice. The 2024–2025 revision cycle includes focus groups with 160 parents from migrant farmworker families in the Rio Grande Valley, whose input shaped new units on La Migración de las Mariposas (monarch migration) and Los Trabajadores de la Tierra (farmworker tools and seasons). As Dr. Sánchez states in her 2023 keynote at the National Head Start Conference: ‘Curriculum isn’t something we deliver to children. It’s something we build with families, elders, and children themselves—brick by brick, word by word, season by season.’

Jesusita exemplifies how early childhood curriculum can be both rigorously evidence-based and profoundly human-centered. Its success lies not in standardized pacing or uniform materials—but in honoring the linguistic richness, cultural wisdom, and developmental realities of the children and families it serves. By anchoring instruction in local ecology, intergenerational knowledge, and scientifically sound pedagogy, Jesusita offers a replicable model for equitable early education—one that meets children where they are, in language, culture, and cognition.
Its enduring impact is visible in subtle but powerful ways: a 4-year-old confidently explaining photosynthesis using both sol and sun; a grandmother sharing her chile roasting technique with classroom volunteers; a teacher revising a lesson plan after hearing a child’s story about helping harvest maíz azul with abuelo. These moments—grounded in respect, reciprocity, and developmental precision—are where Jesusita’s philosophy becomes practice, and where early learning transforms into lifelong belonging.
For educators considering adoption, the path begins not with purchasing materials but with listening—with visiting local farms, attending community festivals, consulting with elders, and reviewing district-level data on home language use and kindergarten readiness gaps. Jesusita does not prescribe answers; it invites dialogue, documentation, and collective responsibility for nurturing every child’s full potential.
Implementation fidelity is measured not by checklist completion but by whether children initiate conversations in their home language, whether families contribute stories and artifacts to classroom displays, and whether teachers adjust lesson timing based on observed engagement—not predetermined scripts. This is curriculum as living practice, not static product.
The Jesusita model demonstrates that high-quality early education need not be expensive, exclusionary, or externally imposed. When rooted in place, relationship, and research, it becomes a catalyst for equity—proving that the most effective tools for learning are often already present: in the soil, the stories, the songs, and the strength of community.
As New Mexico’s Early Learning Advisory Council affirmed in its 2023 Strategic Plan, ‘The best curriculum is not the one with the most pages or the highest price tag—it is the one that helps children see themselves as thinkers, speakers, creators, and contributors from day one.’ Jesusita delivers exactly that.
Its legacy is not confined to lesson plans or test scores. It lives in the confidence of a child who presents a bilingual science report to her family; in the pride of a teacher who co-authors a unit with her students’ grandparents; in the quiet certainty that every child arrives ready to learn—just as they are, in the language and culture that carry their history and hold their future.
