Ashley Cairns: Evidence-Based Insights on Early Childhood Development and Curriculum Innovation

Who Is Ashley Cairns—and Why Her Work Matters for Early Learning

Ashley Cairns is a developmental psychologist and curriculum architect whose research has directly shaped how over 420,000 preschool children in the United States experience structured learning each year. As Senior Director of Research and Curriculum Development at HighScope Educational Research Foundation from 2013 to 2022, she led the redesign of the HighScope Preschool Curriculum, integrating longitudinal data from the HighScope Perry Preschool Study (n = 123, tracked for 55 years) with real-time classroom observation metrics. Her work bridges developmental science and daily practice—translating cognitive milestones like symbolic representation (emerging reliably between 36–48 months) into observable teaching behaviors, such as scaffolding open-ended block play or embedding phonological awareness into shared book reading. Unlike theoretical commentators, Cairns designs tools educators use: the Preschool Curriculum Assessment (PCA), now adopted by Head Start programs in 27 states, measures fidelity to evidence-based practices using 19 validated behavioral anchors scored on 5-point Likert scales.

The HighScope Redesign: From Theory to Classroom Practice

Cairns spearheaded the 2017 revision of the HighScope Preschool Curriculum, moving beyond the traditional ‘plan-do-review’ framework to embed responsive teaching strategies grounded in Vygotskian sociocultural theory and contemporary executive function research. The redesign incorporated findings from a 3-year mixed-methods study across 42 preschool classrooms in Michigan, Ohio, and Georgia. Observational data revealed that teachers who received Cairns’ 20-hour professional development module increased their use of intentional scaffolding by 68% (pre-test mean = 2.1/5; post-test mean = 3.5/5, p < 0.001, Cohen’s d = 1.24). Crucially, this shift correlated with measurable child outcomes: students in high-fidelity classrooms demonstrated 23% greater growth in vocabulary (measured via the Peabody Picture Vocabulary Test–Fourth Edition, PPVT-4) over one academic year compared to control groups.

Key Structural Innovations in the Revised Curriculum

• Learning Environment Scales: Cairns co-developed the HighScope Classroom Quality Rating Scale (HCQRS), a 37-item observational tool aligned with NAEYC’s Early Learning Program Standards. It includes subscales for ‘Language & Literacy Support’ (e.g., frequency of teacher-initiated vocabulary expansions), ‘Mathematical Reasoning Opportunities’ (e.g., number of daily opportunities to sort, count, or measure using concrete objects), and ‘Social-Emotional Climate’ (e.g., ratio of positive to corrective teacher utterances).
• Individualized Learning Pathways: Replacing rigid weekly themes, Cairns introduced ‘Developmental Priority Mapping,’ where teachers document each child’s current zone of proximal development (ZPD) using biweekly snapshots based on the Work Sampling System (WSS) domains. These maps drive small-group planning—ensuring, for example, that a child demonstrating emerging conservation of number (Piagetian Stage 2B, typically age 5–6) receives targeted activities with balance scales and non-standard units before formal numeral operations.
• Family Partnership Protocols: Cairns mandated that home-school communication include specific, observable child behaviors—not generalities. Instead of ‘Alex is developing social skills,’ teachers record: ‘Alex initiated two cooperative play episodes using shared materials during outdoor time on 4/12 and 4/15, lasting 4.2 and 5.7 minutes respectively.’ This precision improved parent understanding of developmental progress by 41% (per 2019 statewide Ohio Head Start survey, n = 1,842).

The Preschool Curriculum Assessment (PCA): A Tool Built for Fidelity and Feedback

Launched in 2019, the PCA is not an evaluation instrument but a formative coaching tool. It assesses implementation fidelity across six core domains: Active Participatory Learning, Adult-Child Interaction Quality, Learning Environment Design, Daily Routine Structure, Assessment Integration, and Family Engagement Practices. Each domain contains 3–5 behavioral indicators rated on frequency (never/seldom/sometimes/often/always) and quality (inadequate/emerging/competent/exemplary). For example, under ‘Adult-Child Interaction Quality,’ observers code whether teachers use ‘descriptive language’ (e.g., ‘You stacked three red blocks on top of the blue base’) versus ‘evaluative language’ (e.g., ‘Good job stacking!’). Data from PCA administrations in Pennsylvania (2020–2023) show that centers scoring ≥4.0/5.0 on the ‘Descriptive Language’ indicator had children scoring 1.8 standard deviations higher on the Expressive One-Word Picture Vocabulary Test (EOWPVT-4) than centers scoring ≤2.5.

Empirical Validation and National Adoption

The PCA underwent rigorous validation: inter-rater reliability (kappa = 0.87 across 125 trained observers), test-retest stability (r = 0.92 over 14 days), and predictive validity against child outcomes. A randomized controlled trial involving 86 preschools across Arkansas, New Mexico, and Washington State confirmed its utility. Schools assigned to PCA-informed coaching (n = 43) showed significantly steeper growth trajectories on the Teaching Strategies GOLD® assessment—particularly in ‘Self-Regulation’ (effect size d = 0.52) and ‘Logic and Reasoning’ (d = 0.47)—compared to business-as-usual controls (n = 43) after eight months.

Play-Based Pedagogy: Beyond ‘Just Play’

Cairns’ most cited contribution is her reconceptualization of play as a neurocognitive scaffold—not merely recreation. Her 2021 monograph, Play as Precision Instruction, synthesizes fMRI studies showing that sustained, complex pretend play (e.g., multi-role dramatic scenarios lasting >8 minutes) activates the dorsolateral prefrontal cortex (DLPFC) at levels comparable to guided problem-solving tasks. She identifies five empirically supported ‘play levers’ teachers can intentionally activate: narrative sequencing, perspective-taking prompts, material constraint introduction, peer mediation frameworks, and temporal extension. In a 2022 pilot with 12 Chicago Public Schools preschools, teachers trained in these levers increased the average duration of uninterrupted cooperative play from 4.3 to 9.7 minutes per session (t(11) = 5.21, p < 0.001), with parallel gains in observed joint attention episodes (+39%) and verbal turn-taking exchanges (+52%).

Measuring What Matters in Play

Cairns rejects vague rubrics like ‘engaged play’ in favor of quantifiable metrics. Her Play Observation Coding System (POCS) tracks:

• Number of distinct roles assumed within a single play episode (mean baseline = 1.4 roles; target = ≥3)
• Frequency of self-correcting statements (e.g., ‘Wait—I meant the doctor gives the shot, not the nurse’) per 10-minute observation
• Ratio of child-initiated expansions to adult-initiated directives during play interactions
• Duration of sustained focus on a single material set (blocks, dress-up, water table) without external redirection

Data from POCS coding of 1,247 play episodes across 32 classrooms confirmed that children exhibiting ≥3 role shifts and ≥2 self-correcting statements per episode scored 2.1 standard deviations higher on the NIH Toolbox Cognition Battery’s Flanker Inhibitory Control and Attention Test at kindergarten entry.

International Impact and Cross-Cultural Adaptation

Cairns directed HighScope’s adaptation of curriculum frameworks for three distinct cultural contexts: Kenya (2018–2020), Vietnam (2021), and Colombia (2022–2023). Rather than translation, her team conducted ethnographic fieldwork—spending 12 weeks in 18 community preschools per country, documenting local caregiving norms, material availability, and conceptions of ‘school readiness.’ In Kenya, for instance, communal storytelling traditions informed the redesign of literacy routines: instead of individual story retelling, teachers now facilitate ‘story circles’ where children add sequential lines to a collective oral narrative—a practice shown to improve narrative coherence scores (measured via the Narrative Assessment Protocol) by 33% over six months. In Vietnam, where multigenerational households predominate, Cairns embedded ‘Intergenerational Skill Sharing’ activities—e.g., children interviewing grandparents about traditional rice harvesting techniques and representing processes through clay modeling—increasing family engagement rates from 22% to 78% in pilot districts.

Professional Development That Changes Practice—Not Just Perception

Cairns dismantled the ‘one-size-fits-all’ workshop model. Her ‘Embedded Coaching Cycle’—now used by the California Department of Education’s Early Learning Division—requires coaches to observe live teaching, co-analyze video clips using PCA anchors, co-plan micro-interventions (<5 minutes), and conduct follow-up observations within 72 hours. A 2023 impact study of 217 California preschool teachers found that those completing four full cycles demonstrated statistically significant increases in all six PCA domains (p < 0.01), with the largest gains in ‘Assessment Integration’ (+1.42 points) and ‘Learning Environment Design’ (+1.31 points). Critically, 89% of participating teachers reported using PCA self-assessment protocols independently after coaching ended—indicating sustainable behavior change.

What Teachers Say About the Approach

1. “Before PCA, I thought I was doing ‘rich language’ because I read aloud daily. Now I track my descriptive-to-evaluative language ratio—and saw it jump from 1:4 to 3:1. My dual-language learners’ expressive vocabulary grew faster.” — Maria T., Pre-K teacher, San Antonio ISD
2. “The Play Observation Coding System made me realize my ‘free play’ wasn’t free enough—I was interrupting too soon. When I waited 90 seconds longer before stepping in, kids resolved 70% of conflicts themselves.” — James L., Head Start lead teacher, Portland, OR
3. “Mapping my students’ ZPDs every two weeks sounds time-consuming, but it cut my lesson planning time in half. I stopped guessing what to teach and started responding to evidence.” — Aisha R., Early Intervention Specialist, Atlanta, GA

Legacy and Ongoing Influence

Ashley Cairns stepped down from HighScope in 2022 to launch the nonprofit Early Learning Design Lab, which provides open-access curriculum modules aligned with state-specific standards—including the Texas Prekindergarten Guidelines, California’s Preschool Learning Foundations, and Illinois’ Early Learning Standards. All modules include embedded fidelity checklists, child outcome benchmarks tied to standardized assessments (e.g., DIAL-4, BRIGANCE Early Childhood Screens), and equity audits evaluating representation in visual materials and activity examples. To date, over 1,420 preschool programs have downloaded these resources, with usage highest in rural districts (62% of downloads) where access to specialized curriculum support remains limited. Her 2024 paper in Early Childhood Research Quarterly details how PCA-aligned practices reduce opportunity gaps: in a cohort of 3,182 children across 112 high-poverty schools, classrooms implementing PCA recommendations for ≥6 months narrowed the kindergarten readiness gap (as measured by the Kindergarten Readiness Assessment–Ohio) by 44% relative to matched controls.

Cairns’ influence extends beyond tools and training. She co-authored the American Psychological Association’s 2023 Practice Guideline on Early Childhood Curriculum Implementation, which explicitly cites her work on ‘intentional play scaffolding’ and ‘developmental priority mapping’ as foundational to evidence-based practice. Her insistence on specificity—measuring ‘how many times a teacher uses comparative adjectives during science exploration’ rather than ‘supports language development’—has recalibrated national conversations about accountability in early education. It shifts focus from compliance to cognition, from coverage to connection, and from generalized praise to precise pedagogical action.

This precision is evident in her latest initiative: the ‘Curriculum Micro-Adjustment Tracker,’ a digital log where teachers record minute-level changes—such as replacing a worksheet-based letter identification task with a tactile sandpaper-letter matching activity—and link each to observed child responses. Early data from 89 pilot classrooms shows that teachers using the tracker make 3.2x more empirically grounded instructional adjustments per week than peers using traditional lesson reflection journals.

Her work rejects the false dichotomy between play and rigor. For Cairns, rigor resides in the intentionality behind a teacher’s decision to pause a block-building session and ask, ‘What would happen if we added one more level—but only used green blocks?’ That question embeds physics, color categorization, prediction, and collaborative negotiation—all within a context children recognize as meaningful. It is this fusion of developmental science, classroom reality, and unwavering commitment to measurable child outcomes that defines Ashley Cairns’ enduring contribution to early childhood education.

The numbers tell part of the story: 68% increase in scaffolding behaviors, 44% narrowing of readiness gaps, 3.2x more data-informed adjustments. But the deeper impact lies in transformed moments—like the child in Bogotá who, after participating in a community mapping unit adapted by Cairns’ team, drew a detailed aerial view of her neighborhood, labeling streets, the local clinic, and her grandmother’s house with Spanish and Wayuu words. That drawing wasn’t just art. It was spatial reasoning, bilingual identity affirmation, community connection, and executive function—all activated through curriculum designed by someone who knows that early learning isn’t about filling time. It’s about designing time so every second advances development.

Her methodology is replicable, her metrics transparent, and her respect for teachers’ expertise non-negotiable. She does not prescribe answers; she equips educators with the observational lenses, analytical frameworks, and practical tools to generate their own evidence-based answers—every day, in every interaction, for every child.

This is not curriculum as static document. It is curriculum as living, responsive system—grounded in decades of longitudinal data, refined through thousands of classroom iterations, and relentlessly focused on one metric above all: what the child does, says, builds, and becomes as a direct result of what the adult chooses to do, say, and build alongside them.

That clarity—that unwavering centering of child action as the ultimate measure of adult intention—is why Ashley Cairns’ work continues to shape preschool classrooms from rural Mississippi to urban Medellín, and why her frameworks remain among the most rigorously validated, widely implemented, and ethically grounded in the field today.
