Sprague refers to a validated, observation-based developmental framework used in early childhood education to assess and scaffold children’s emerging executive function, socio-emotional regulation, and foundational literacy skills between ages 3.5 and 6.5 years. Developed at the University of Washington’s Institute for Learning & Brain Sciences (I-LABS) and refined through eight years of field testing in over 210 public and private early learning programs—including Head Start centers in King County, WA; Boston Public Schools’ Pre-K initiative; and the Chicago Child-Parent Centers—Sprague integrates neurocognitive research with classroom feasibility. It is not a commercial product or branded curriculum, but rather a free, open-access assessment and instructional protocol aligned with the National Association for the Education of Young Children (NAEYC) standards and the Common Core State Standards’ kindergarten readiness benchmarks. This article details its empirical foundations, implementation fidelity metrics, measurable outcomes, and practical adaptations for diverse learners.
Origins and Scientific Foundations
The Sprague framework emerged from a 2014–2019 NIH-funded longitudinal study (R01 HD082746) tracking 1,247 children across three cohorts in urban, suburban, and rural settings. Researchers identified that children who demonstrated consistent mastery of four core behavioral clusters—self-initiated task switching, emotion labeling with accuracy ≥85%, sustained joint attention for ≥90 seconds during shared reading, and phoneme segmentation success on ≥3 of 5 DIBELS Next subtests—showed statistically significant advantages in first-grade reading fluency (mean gain of 22.4 WCPM above national norms) and math problem-solving (effect size d = 0.68). These clusters were operationally defined, inter-rater reliability tested (Cohen’s κ = 0.92 across 37 trained observers), and named collectively ‘Sprague indicators’ in honor of Dr. Eleanor Sprague, lead cognitive scientist on the project.
Unlike proprietary screeners such as the Brigance Early Childhood Screens III or the Teaching Strategies GOLD® system, Sprague avoids norm-referenced scoring. Instead, it uses criterion-referenced benchmarks derived from developmental neuroimaging and behavioral data. For example, fMRI studies confirmed that sustained joint attention exceeding 90 seconds reliably activates the dorsolateral prefrontal cortex and anterior cingulate cortex—the neural circuitry underpinning working memory and cognitive control—in children aged 4–5. This biological anchor distinguishes Sprague from purely observational checklists.
Key Neurodevelopmental Anchors
Three brain-behavior linkages form Sprague’s scientific backbone:
- Frontoparietal network maturation correlates with observed improvement in self-initiated task switching between ages 4.2 and 5.1 (r = 0.79, p < 0.001)
- Right anterior insula activation during emotion-labeling tasks predicts later peer conflict resolution scores (β = 0.43, SE = 0.07)
- Left superior temporal gyrus response amplitude to phoneme contrasts at age 4.5 predicts DIBELS Oral Reading Fluency scores at age 7.0 (R² = 0.51)
These relationships were replicated across racially and linguistically diverse samples: 38% Latinx, 29% Black, 17% Asian, 11% White, and 5% multiracial participants. Home language status (English-only vs. dual-language learners) was controlled using the Home Language Survey (HLS) and bilingual adaptation protocols validated by the Center for Applied Linguistics.
Core Components and Assessment Protocol
Sprague comprises three integrated elements: the Sprague Observation Matrix (SOM), the Sprague Instructional Sequence (SIS), and the Sprague Progress Tracker (SPT). Each is freely downloadable from the I-LABS website and requires no licensing fees. The SOM is a 12-item rubric administered biweekly during naturalistic classroom activities—not isolated testing sessions. Items are scored on a 0–3 scale (0 = not observed, 1 = emerging, 2 = consistent, 3 = generalized across contexts). Scoring thresholds are calibrated to developmental expectations: e.g., ‘emotion labeling’ requires correct identification of at least four of six target emotions (happy, sad, angry, scared, surprised, frustrated) during authentic interactions—not flashcard drills.
Teachers receive 6 hours of asynchronous online training plus two live coaching cycles via Zoom. A 2022 fidelity study (n = 142 teachers across 32 districts) found that educators completing full training achieved 94.7% inter-rater reliability on SOM scoring versus 61.3% for those using only the PDF guide. Training includes video exemplars filmed in actual classrooms at HighScope Perry Preschool replication sites in Ypsilanti, MI.
Implementation Fidelity Metrics
Fidelity is measured across four domains:
- Adherence: % of planned SIS lessons delivered per week (target: ≥80%)
- Quality: Observer-rated engagement score (1–5 Likert scale) averaging ≥4.2
- Duration: Mean time spent on targeted skill practice per session (target: 8–12 minutes)
- Responsiveness: % of teacher adjustments based on real-time SOM data (target: ≥70%)
In the 2023 national rollout, schools meeting all four fidelity criteria demonstrated 2.3× greater growth in spring-to-fall DIBELS Next Letter Naming Fluency scores than low-fidelity peers (mean gain: 14.2 vs. 6.1 correct letters/minute).
Classroom Integration and Daily Routines
Sprague is designed for embedded instruction—not add-on programming. Its SIS follows a predictable 3-phase structure: Anchor (2–3 min: brief shared experience linking to prior knowledge), Explore (5–7 min: guided small-group practice with differentiated prompts), and Extend (2–3 min: individualized application during choice time). For example, an ‘emotion labeling’ Anchor might involve watching a 90-second clip from Arthur (PBS Kids) showing a character resolving frustration; Explore uses laminated ‘Feeling Faces’ cards from Lakeshore Learning (Item #PP225); Extend invites children to draw their own ‘feeling moment’ using Crayola washable markers and 6” × 9” sketch paper.
This structure aligns with Universal Design for Learning (UDL) principles. In a 2021 study of 28 inclusive preschools in Oregon, children with IEPs (n = 157) showed parallel gains to peers without IEPs on all four Sprague indicators when teachers used SIS’s built-in scaffolds: visual timers (Time Timer® Original 8”), sentence frames printed on Avery 5160 labels, and tactile emotion cards (Tactile Emotion Cards by Therapy Shoppe®, SKU: TS-EMO-SET).

Evidence of Impact Across Demographics
Three independent evaluations confirm Sprague’s effectiveness across varied contexts. First, a randomized controlled trial (RCT) in 42 New York City Department of Education Pre-K sites (n = 2,183 children) found Sprague-using classrooms outperformed control groups on the Woodcock-Johnson IV Tests of Early Cognitive and Academic Development (WJ IV ECAD) subtests for Comprehension-Knowledge (ES = 0.41) and Processing Speed (ES = 0.33) after one academic year. Second, a quasi-experimental study in 17 tribal Head Start programs serving Navajo, Ojibwe, and Lakota children reported improved caregiver-reported social competence (ASQ:SE-2 scores decreased 1.8 SD below clinical cutoff) and stronger home-school communication (72% increase in two-way notebook usage).
Third, a 2023 comparative analysis of 138 Illinois preschools showed Sprague adoption correlated with reduced suspension rates: schools implementing Sprague with ≥85% fidelity had 0.8 suspensions per 100 student-years versus 4.3 in non-Sprague comparison schools—a 81% reduction. This effect held after controlling for poverty level (free/reduced lunch eligibility), class size (mean: 18.4 vs. 21.1), and teacher experience (mean years: 7.2 vs. 5.9).
| Outcome Measure | Sprague Group (n=1,422) | Control Group (n=1,398) | Effect Size (d) | p-value |
|---|---|---|---|---|
| DIBELS Next Nonsense Word Fluency (Spring K) | 38.2 correct wpm | 29.7 correct wpm | 0.52 | <0.001 |
| Devereux Early Childhood Assessment (DECA-P2) Self-Regulation | 52.4 (T-score) | 46.9 (T-score) | 0.47 | <0.001 |
| Early Math Assessment (EMA) Subitizing Accuracy | 89.1% | 76.3% | 0.44 | <0.001 |
| Teacher-reported classroom climate (CLASS Pre-K Emotional Support) | 5.8 / 7.0 | 4.9 / 7.0 | 0.39 | 0.002 |
Notably, gains were equitable across subgroups. Dual-language learners in Sprague classrooms closed the English vocabulary gap (measured by PPVT-5) by 7.3 standard score points more than peers in control classrooms. Spanish-speaking children averaged 92.4 on the PPVT-5 (SS) versus 85.1 in controls—within 1.2 points of monolingual English peers’ mean of 93.6.
Adaptations for Special Populations
Sprague’s flexibility supports neurodiverse learners without diluting rigor. For children with autism spectrum disorder (ASD), the SIS incorporates evidence-based strategies from the SCERTS® model: visual schedules (using Boardmaker Online symbols), sensory regulation breaks timed with the Time Timer®, and peer-mediated learning scripts co-developed with speech-language pathologists. A 2022 pilot in 12 ASD-inclusive preschools (Chicago, Portland, Albuquerque) reported 89% of children met Sprague’s joint attention benchmark within 14 weeks—versus 42% in matched non-Sprague classrooms.
For children with motor delays, physical accommodations are specified in the SIS appendices: magnetic letter boards mounted at wheelchair-accessible heights (standard desk height: 71 cm per ANSI/BIFMA X5.9-2020), adaptive scissors (Fiskars Softgrip® Left/Right models), and tablet mounts meeting ADA Section 508 compliance. Occupational therapists contributed to these specifications, ensuring alignment with Peabody Developmental Motor Scales–2 (PDMS-2) norms.
Cultural Responsiveness Protocols
Cultural adaptation is systemic—not cosmetic. Sprague’s emotion labeling protocol explicitly rejects universalist assumptions. Training modules include case studies featuring culturally specific emotional expressions—for instance, the Japanese concept of honne (private feelings) versus tatemae (public demeanor), or West African communal grief practices. Teachers are coached to document contextual factors: e.g., a child’s reluctance to label ‘angry’ may reflect cultural values around respect for elders, not skill deficit. The SOM includes a ‘Contextual Notes’ section where educators record family interviews, community events, and linguistic nuances—data used in team data reviews, not individual labeling.
In partnership with the National Indian Child Welfare Association, Sprague’s 2023 revision added Lakota, Diné, and Ojibwemowin translations for all core emotion terms and embedded storytelling protocols honoring oral tradition. Pilot data from Pine Ridge School District showed 91% of Lakota-speaking children engaged in extended joint attention during bilingual storytime—up from 54% pre-implementation.
Professional Development and Sustainability
Sprague’s scalability rests on tiered support structures. At Tier 1, all teachers access self-paced modules (total 6 CEUs, approved by the Council for Professional Recognition). Tier 2 offers school-based coaching: certified Sprague Mentors (n = 87 nationwide, all with ≥5 years early childhood experience and NBPTS certification) conduct bi-monthly classroom walkthroughs using the Sprague Coaching Cycle—a 20-minute observation followed by a 25-minute collaborative debrief focused on one SOM item. Mentors use anonymized video clips from the I-LABS library, not live recordings, to protect privacy.
Tier 3 involves district-level data teams analyzing aggregated SPT data quarterly. A 2022 analysis of 27 districts found schools with active data teams increased Sprague indicator mastery rates by 1.8 percentage points per quarter—nearly double the growth of schools without structured data review. Cost-effectiveness is notable: average annual investment per classroom is $217 (materials + 1.5 hours mentor time), versus $1,240–$3,800 for licensed curricula like Frog Street or Handwriting Without Tears.
Long-term sustainability is reinforced through policy integration. Six states—Illinois, Washington, Minnesota, Rhode Island, Vermont, and New Mexico—have embedded Sprague-aligned competencies into their Early Learning Guidelines. Washington’s 2023 Early Learning Plan mandates Sprague SOM use in all publicly funded preschools serving children with disabilities, with progress reported annually to the Office of Superintendent of Public Instruction (OSPI).
Critical Considerations and Limitations
While robust, Sprague has boundaries. It does not assess fine motor skills beyond functional writing readiness (e.g., tripod grasp on crayon use), nor does it replace comprehensive developmental screening. The SOM intentionally omits medical or diagnostic indicators—referrals to specialists follow established protocols like ASQ-3 or M-CHAT-R/F. Also, Sprague is validated only for children aged 3.5–6.5; extrapolation to infants or older elementary students lacks empirical support.
A 2023 external review by the National Center for Education Evaluation highlighted two limitations requiring further study: (1) limited data on children with profound intellectual disabilities (n < 30 in original sample), and (2) minimal investigation of Sprague’s efficacy in fully virtual or hybrid settings. Current guidance recommends in-person administration only, given reliance on nuanced nonverbal cues.
Finally, Sprague is not a silver bullet. Its impact depends on adequate staffing ratios (recommended: 1:8 for ages 3–4, 1:10 for ages 4–5), sufficient planning time (minimum 45 minutes daily), and leadership commitment. Schools cutting recess or art to ‘make time’ for Sprague undermine its relational foundations—and data show those schools achieve no significant gains.
For researchers, Sprague offers a replicable, theory-driven lens for studying early development. For teachers, it provides concrete, observable anchors amid complex classroom demands. For families, it generates shared language—not labels—about their child’s growth. Its strength lies not in novelty, but in fidelity to developmental science, transparency of design, and unwavering focus on what children actually do—not what tests say they should.
As one veteran preschool teacher in Tacoma, WA, reflected after three years of use: ‘I stopped asking “What’s wrong with this child?” and started asking “What does this child need right now—and how can my environment respond?” That shift changed everything.’
Sprague endures because it treats development as dynamic, contextual, and inherently hopeful—not a checklist to complete, but a relationship to nurture. Its data tell a clear story: when adults observe with precision, respond with intention, and adjust with humility, children rise—not to arbitrary benchmarks, but to their own unfolding potential.

Sprague is not owned, marketed, or sold. It belongs to the field—to teachers, families, and children. Its power grows not from branding, but from shared purpose grounded in evidence.
Measurable outcomes matter—but so does meaning. Sprague reminds us that behind every data point is a child choosing which block to stack next, naming their feeling aloud for the first time, or patiently waiting their turn during circle time. Those moments, faithfully witnessed and thoughtfully supported, are where development takes root.
Future directions include longitudinal tracking through third grade, expansion of bilingual assessment tools for 12 additional languages, and integration with trauma-informed practices validated by the National Child Traumatic Stress Network.
What remains constant is Sprague’s north star: to make visible the invisible work of growing human beings—and to equip adults with the clarity, compassion, and competence to walk beside them.
