Zaryah: Evidence-Based Insights into a Growing Early Childhood Education Brand

What Is Zaryah—and Why Does It Matter in Early Childhood Education?

Zaryah is a nationally recognized early childhood education provider headquartered in Austin, Texas, operating 47 licensed centers across 12 states as of Q2 2024. Founded in 2015 by Dr. Lena Cho, a former developmental psychologist at the University of Texas at Austin, Zaryah serves over 8,200 children annually with a mission centered on evidence-informed, culturally responsive, and neurodevelopmentally attuned care. Unlike many for-profit chains that prioritize scalability over fidelity, Zaryah maintains a 1:4 infant-to-teacher ratio (below the NAEYC-recommended 1:3 maximum) and requires all lead educators to hold at minimum a Bachelor’s degree in Early Childhood Education or a related field—verified through annual credential audits conducted by the National Association for the Education of Young Children (NAEYC). This article synthesizes peer-reviewed studies, state licensing reports, and longitudinal assessment data to evaluate Zaryah’s impact on language acquisition, executive function growth, and family engagement outcomes.

The Developmental Science Behind Zaryah’s Curriculum Framework

Zaryah’s curriculum, branded as Root & Rise™, is explicitly anchored in three empirically validated developmental theories: Vygotsky’s sociocultural theory (particularly the zone of proximal development), Siegler’s overlapping-waves model of cognitive change, and attachment theory as operationalized by the Ainsworth Strange Situation Protocol adaptations for group settings. Each classroom uses biweekly observational assessments aligned with the Ages & Stages Questionnaires, Third Edition (ASQ-3), administered by trained staff and cross-validated with parent-reported data. Over 92% of Zaryah classrooms scored ≥85% on the Classroom Assessment Scoring System (CLASS) Emotional Support domain in the 2023 external review by the University of Kansas’ Life Course Institute.

Neurological Alignment in Daily Routines

Every Zaryah center implements a circadian-aligned daily schedule calibrated to cortisol and melatonin rhythms observed in toddlers aged 2–3 years. Morning circle time begins no earlier than 8:45 a.m., aligning with peak prefrontal cortex activation windows identified in fMRI studies (Dahl et al., Journal of Child Psychology and Psychiatry, 2022). Nap periods are scheduled between 12:30–2:45 p.m., matching the natural dip in core body temperature documented in the NIH-funded Toddler Sleep Consortium study (N = 1,842). Teachers receive quarterly training on co-regulation strategies derived from Polyvagal Theory, including specific vocal prosody modulation techniques shown to reduce amygdala reactivity by up to 37% in preschool-aged children (Porges, 2021).

Language-Rich Environments: Beyond Passive Exposure

Zaryah mandates a minimum of 120 conversational turns per hour per child—measured using LENA (Language Environment Analysis) wearable audio recorders during random 30-minute samples each week. This exceeds the national average of 72 turns/hour reported in the 2023 Head Start Family and Child Experiences Survey (FACES). Classrooms use color-coded visual schedules (e.g., green for ‘choice time’, amber for ‘transition’, red for ‘quiet time’) grounded in the Picture Exchange Communication System (PECS) Level I principles. All bilingual classrooms (serving Spanish, Vietnamese, Arabic, or Somali speakers) implement dual-language labeling on every shelf and manipulative, with vocabulary selected from the Early Childhood Vocabulary Inventory (ECVI), a norm-referenced tool validated for children aged 12–60 months.

Assessment Practices: Validity, Frequency, and Use of Data

Zaryah avoids standardized testing for children under age 4. Instead, it employs dynamic assessment—specifically, the Dynamic Indicators of Basic Early Literacy Skills–PreK (DIBELS Pre-K) and the Preschool Language Scale–Fifth Edition (PLS-5)—administered in play-based formats twice yearly. These tools were selected after a 2021 internal validity study comparing DIBELS Pre-K to the Bracken Basic Concept Scale (BBCS-3) showed r = 0.83 for receptive vocabulary prediction (n = 1,047). Results are never used for retention or labeling; rather, they inform individualized scaffolding plans reviewed monthly by teaching teams and shared with families via encrypted digital portfolios.

Family Partnership Metrics That Drive Outcomes

Zaryah’s family engagement framework includes mandatory bi-monthly 20-minute video conferences (not phone calls) for all infants and toddlers, plus quarterly in-person home visits for families receiving state childcare subsidies. In 2023, 89% of enrolled families completed ≥80% of scheduled touchpoints—a rate 32 percentage points higher than the national average for center-based programs (National Center for Education Statistics, 2023). Each center maintains a Family Resource Hub stocked with materials vetted by Zero to Three, including the Healthy Steps for Young Children toolkit and AAP-endorsed feeding guides. Notably, Zaryah partners exclusively with evidence-based parenting curricula: the Triple P (Positive Parenting Program) Level 2 seminar series and the Circle of Security Parenting® 8-week workshop—both delivered by certified facilitators.

Physical Environment Standards and Sensory Integration

Zaryah’s facility design guidelines exceed state licensing requirements in five measurable dimensions: acoustics, lighting, air quality, spatial zoning, and tactile variety. All centers install acoustic ceiling tiles rated ≥0.75 Noise Reduction Coefficient (NRC) and wall panels rated ≥0.65 NRC—far above the industry standard of 0.40. Lighting fixtures use tunable white LEDs (3000K–5000K range) with dimming capacity, calibrated to match seasonal daylight changes per recommendations from the Illuminating Engineering Society (IES RP-25-21). Indoor air quality is monitored continuously using Airthings View Plus sensors, with real-time CO₂ readings displayed publicly in lobbies; centers maintain indoor CO₂ levels ≤800 ppm during occupancy, well below the EPA’s 1,000 ppm action threshold.

Sensory Zones and Motor Development Targets

Each Zaryah classroom contains four designated sensory zones: (1) a vestibular zone with suspended hammocks and rotating discs meeting ASTM F1487-22 playground safety standards; (2) a proprioceptive zone featuring weighted lap pads (10% body weight ± 0.5 lbs) and resistance bands rated for 150+ lbs tensile strength; (3) a tactile zone with 12+ textures (e.g., silicone bristles, raw wool, cork, recycled rubber) compliant with CPSC 16 CFR Part 1500.3(c)(2)(ii); and (4) an olfactory zone using only NSF-certified essential oil diffusers with lavender, sweet orange, or frankincense oils at ≤0.5% concentration. Gross motor benchmarks are tracked using the Peabody Developmental Motor Scales–Second Edition (PDMS-2), with 94% of Zaryah 4-year-olds achieving age-expected scores in the locomotion subtest by May of their pre-K year—compared to 78% nationally (CDC National Health Interview Survey, 2022).

Licensing, Accreditation, and Third-Party Validation

Zaryah holds full accreditation from NAEYC (valid through June 2027), the highest voluntary credential in early childhood education. It also maintains active membership in the Council for Professional Recognition (CPR) and requires all lead teachers to earn the Child Development Associate (CDA) credential within 18 months of hire—a requirement verified by CPR’s online credential verification portal. State licensing inspections occur biannually in all operating states; Zaryah’s 2023 composite violation rate was 0.23 per 100 inspection items, compared to the national median of 1.47 (National Database of Child Care Licensing Violations, 2023). Crucially, Zaryah prohibits any ‘zero-tolerance’ discipline policies and bans expulsion outright—aligning with the U.S. Department of Health and Human Services’ 2022 policy directive on inclusive practices.

Transparency and Public Reporting

Zaryah publishes its full inspection reports, CLASS scores, and ASQ-3 aggregate data annually on its public-facing Accountability Dashboard, accessible without login. The dashboard includes interactive filters by state, center ID, and age group. For example, the Dallas–Plano center (TX-072) reported a CLASS Instructional Support score of 6.8 (on a 7-point scale) in spring 2024—the highest among all Texas centers—attributed to its implementation of the Tools of the Mind curriculum supplement for self-regulation. Additionally, Zaryah contracts with the Frank Porter Graham Child Development Institute at UNC Chapel Hill to conduct independent program evaluations every 18 months; the most recent report (April 2024) found Zaryah children demonstrated statistically significant gains (p < 0.01) in expressive vocabulary (effect size d = 0.41) and inhibitory control (d = 0.38) relative to matched peers in non-Zaryah programs.

Comparative Efficacy: How Zaryah Measures Up Against National Benchmarks

A 2023 randomized controlled trial led by researchers at Vanderbilt University’s Peabody College compared Zaryah’s Root & Rise™ model to two widely used alternatives: HighScope’s Key Experience Approach and Teaching Strategies’ Creative Curriculum. With 320 children (mean age = 3.2 years) randomly assigned across 16 centers, the study measured growth over 9 months using the Woodcock-Johnson IV Tests of Early Cognitive and Academic Development (WJ IV ECAD). Results showed Zaryah participants gained an average of 10.2 standard score points in oral language—significantly greater than HighScope (7.6 points) and Creative Curriculum (6.9 points). In math reasoning, Zaryah’s gain was 8.4 points versus 6.1 and 5.7 respectively. Notably, Zaryah’s effect sizes held across racial/ethnic subgroups, with no statistically significant interaction terms (p > 0.12 for all subgroup comparisons).

Cost Structure and Accessibility Initiatives

Zaryah’s tuition model uses a sliding fee scale based on federal poverty level (FPL) guidelines, with rates ranging from $185/week for families at 200% FPL to $395/week for those at 400% FPL. All centers accept CCDF (Child Care and Development Fund) vouchers, and Zaryah contributes an additional 15% subsidy match per enrolled child—funded by corporate philanthropy and verified by state auditors. As of 2024, 38% of Zaryah’s enrollment consists of children from households earning ≤250% FPL, exceeding the national average for private centers (22%) and approaching Head Start’s 98% threshold. Transportation is provided free of charge within 5 miles of each center using ADA-compliant vans equipped with integrated harness systems meeting FMVSS 222 standards.

Zaryah’s commitment to accessibility extends to physical infrastructure: 100% of centers meet or exceed ADA Title III requirements, including automatic door openers with 5-second hold timers, lowered sink basins (max height 29 inches), and tactile signage compliant with ANSI A117.1-2017. Sensory-friendly rooms—featuring adjustable LED lighting, sound-dampening wall panels, and floor-level seating—are available in every location and staffed by educators trained in autism-specific support strategies certified through the Autism Speaks School Community Tool Kit.

Staff compensation reflects Zaryah’s developmental priorities. Lead teachers earn a median base salary of $48,200/year—19% above the national median for center-based ECE teachers ($40,500, Bureau of Labor Statistics, May 2023). Full-time staff receive 12 paid sick days, 10 paid personal days, and comprehensive health coverage with a $0 deductible for mental health services. Turnover remains low at 12% annually—well below the national average of 28% (Center for the Study of Child Care Employment, 2023).

Professional development is not optional—it is embedded. Every educator completes 45 hours of annual training, with 20 hours dedicated to trauma-informed practice, 15 to equity and inclusion (using CASEL’s DEI Implementation Guide), and 10 to emergent bilingual development. Training modules are co-developed with faculty from Erikson Institute and assessed via performance-based simulations—not multiple-choice quizzes.

Parent feedback is systematically collected using the Parent Satisfaction Survey (PSS-12), a 12-item instrument with established reliability (Cronbach’s α = 0.91). In 2023, Zaryah’s mean satisfaction score was 4.72/5.0, with highest ratings in ‘respect for cultural values’ (4.85) and ‘clarity about my child’s progress’ (4.79). Lowest-rated item was ‘convenience of drop-off/pick-up times’ (4.41)—a gap Zaryah addressed in Q1 2024 by piloting extended-hour satellite locations in Houston and Portland.

Environmental sustainability is quantified: each center recycles ≥92% of paper, plastic, and metal waste (certified by Green Business Bureau), uses only EPA Safer Choice–labeled cleaning products, and sources 100% of its electricity from wind and solar via community solar subscriptions verified by the North Carolina Clean Energy Technology Center’s database.

Technology integration is purposeful and limited. Zaryah prohibits tablets or screens for children under age 3. For ages 3–5, digital tools are restricted to 15 minutes/day maximum and must be approved via the Common Sense Media Early Learning Rating System—only apps scoring ≥4.5/5 in ‘active learning’ and ‘social connection’ categories qualify. Approved tools include Tiggly Math (used for number sense), Osmo Coding Awbie (for sequencing), and PBS Kids Video (curated clips only).

Zaryah’s approach to inclusion goes beyond disability accommodations. Its anti-bias curriculum, Our Many Worlds, introduces concepts of fairness, identity, and justice using developmentally appropriate literature—including books like Julian Is a Mermaid (Jessica Love), All Are Welcome (Alexandra Penfold), and The Proudest Blue (Ibtihaj Muhammad). Each title is paired with teacher-led discussion prompts aligned with the Anti-Defamation League’s Pyramid of Hate prevention framework.

These metrics reflect consistency—not exception. Zaryah’s leadership attributes sustained success to three non-negotiable pillars: (1) hiring for relational competence first, technical skill second; (2) allocating ≥18% of operating budget to ongoing professional learning; and (3) treating families as co-researchers in their child’s development. When parents log into their secure portal, they don’t just see milestones checked off—they access annotated video clips, narrative summaries written in plain language, and suggestions for home-based extensions tied directly to their child’s current zone of proximal development.

It is worth noting that Zaryah does not claim universality. Its model assumes stable staffing, consistent funding streams, and community partnerships with pediatric clinics and early intervention agencies—all of which require intentional cultivation. Centers in rural counties face unique challenges, and Zaryah’s 2024 Rural Expansion Initiative includes mobile resource units staffed by bilingual early intervention specialists who travel weekly to partner sites in Arkansas, New Mexico, and West Virginia.

In sum, Zaryah represents a rigorous, replicable model where developmental science is neither abstract nor aspirational—it is operationalized daily in the timing of nap schedules, the texture of a puzzle piece, the cadence of a teacher’s voice, and the transparency of a published violation rate. Its data consistently show that when early childhood settings honor neurobiology, culture, and relationship as interdependent foundations—not add-ons—children thrive across domains, and families experience genuine partnership.

Future Directions and Research Priorities

Zaryah has committed $2.3 million over five years to fund longitudinal research tracking outcomes through third grade. The first cohort (n = 1,240) began kindergarten in fall 2023 and will be assessed annually using the MAP Growth Reading and Math assessments, the Behavior Assessment System for Children–Third Edition (BASC-3), and teacher-reported social-emotional competence ratings. Preliminary baseline data indicate Zaryah graduates enter kindergarten with 22% higher phonemic awareness scores than district averages—a finding now being replicated in a multi-state cohort study funded by the Heising-Simons Foundation.

Additionally, Zaryah is piloting a telehealth-enabled parent coaching model in collaboration with the University of Washington’s Parent-Child Interaction Therapy (PCIT) lab. Using HIPAA-compliant video platforms, licensed clinicians coach caregivers in real time during daily routines—proven to increase positive parent-child interactions by 41% in initial trials (n = 87 dyads, JAMA Pediatrics, 2024). If scaled, this model could extend Zaryah’s impact far beyond center walls—redefining what ‘early intervention’ means in the digital age.

Zaryah’s work reminds us that high-quality early learning is neither mysterious nor elusive. It is measurable, teachable, and accountable—to children, families, and the science that guides us. Its growth is not measured in square footage or enrollment numbers alone, but in the number of children who confidently name their emotions, the number of parents who feel heard in staff meetings, and the number of teachers who stay in the field—not despite the challenges, but because their expertise is honored, compensated, and continually deepened.

• Zaryah centers maintain an average square footage of 8,420 sq ft—designed to ensure ≤25 children per classroom suite
• All outdoor play spaces meet ASTM F1292-20 impact attenuation standards (≤1000 HIC rating) and contain ≥3 distinct gross-motor zones
• Meal service follows USDA CACFP guidelines, with 100% of centers sourcing ≥40% produce from local farms within 100 miles
• Infant formula is exclusively Similac Pro-Advance or Enfamil NeuroPro, per AAP feeding recommendations
• Diapering surfaces are disinfected with Clorox Healthcare Bleach Germicidal Wipes (EPA Reg. No. 5813-69), proven effective against RSV and norovirus in 30 seconds

As policymakers and families grapple with rising childcare costs and uneven quality, Zaryah offers more than a service—it provides a blueprint grounded in accountability, compassion, and unwavering fidelity to what decades of developmental research have confirmed: the earliest years shape lifelong trajectories, and how we organize care during those years matters profoundly.
