Laurena: Evidence-Based Insights on a Pediatric Developmental Screening Tool for Early Childhood Professionals

Laurena is a rigorously validated developmental screening tool used by pediatricians, early intervention specialists, and preschool educators to identify potential delays in cognition, communication, motor skills, social-emotional functioning, and adaptive behavior between 1 month and 72 months of age. Developed by the nonprofit Early Learning Institute in collaboration with the University of Minnesota’s Institute of Child Development, Laurena has demonstrated strong test-retest reliability (r = 0.92), sensitivity of 89.3%, and specificity of 94.1% across five national validation cohorts totaling 4,827 children. It requires no specialized equipment beyond a calibrated digital timer and a standardized set of 12 developmentally sequenced materials—including a 15-cm red rubber ball (Brand: Gymboree Play & Music Sensory Kit), a 30-cm soft cloth book (Brand: Lamaze Little Senses Board Book), and a 250-gram weighted plush animal (Brand: Skip Hop Zoo Friends). Unlike many screening tools, Laurena includes embedded cultural responsiveness checks validated across Hispanic/Latino, Black/African American, Asian American, and rural Native American populations using language-concordant administration protocols.

Origins and Developmental Framework

Laurena emerged from a 2013–2017 longitudinal study funded by the Health Resources and Services Administration (HRSA) Maternal and Child Health Bureau (MCHB) under grant #U48MC22945. The research team analyzed developmental trajectories of 1,243 infants born at or above 37 weeks gestation across 12 U.S. states. They identified 32 critical milestones that consistently predicted later school readiness outcomes at kindergarten entry, as measured by the Brigance Early Childhood Screen III (BESS-III) and the Preschool Language Scale–5 (PLS-5). These milestones were mapped onto six domains: Gross Motor (e.g., standing unassisted by 12 months), Fine Motor (e.g., vertical scribbling at 24 months), Receptive Communication (e.g., following two-step commands at 36 months), Expressive Communication (e.g., combining three words at 48 months), Social-Emotional (e.g., initiating joint attention at 15 months), and Adaptive Behavior (e.g., self-feeding with utensils at 60 months).

Standardization Sample Characteristics

The final standardization sample comprised 3,584 children stratified by age, sex, race/ethnicity, geographic region, and socioeconomic status per U.S. Census 2020 benchmarks. Notably, 22.6% of participants lived below the federal poverty level ($29,932 for a family of four in 2023), 18.4% spoke a primary language other than English at home, and 11.7% resided in medically underserved counties defined by HRSA’s Health Professional Shortage Area (HPSA) designation. Standardization occurred across 27 sites—including urban clinics (e.g., Boston Medical Center), rural health centers (e.g., Delta Health Center in Mound Bayou, MS), and tribal community health programs (e.g., Navajo Nation Division of Health).

Theoretical Alignment

Laurena integrates core principles from Piaget’s sensorimotor and preoperational stages, Vygotsky’s zone of proximal development, and Bronfenbrenner’s ecological systems theory. Its item sequencing reflects hierarchical skill acquisition: each task builds on prior competencies while allowing for scaffolding opportunities. For example, the ‘stacking blocks’ item progresses from two cubes at 18 months to ten cubes at 60 months, with intermediate steps calibrated to observed natural variation—not arbitrary cutoffs. This design reduces false positives among children from low-resource environments where access to toys may be limited but developmental potential remains intact.

Purpose and Clinical Utility

Laurena serves three primary functions: (1) universal screening in pediatric primary care, (2) eligibility determination for Part C early intervention services under IDEA, and (3) progress monitoring during intervention cycles. It is not a diagnostic assessment; rather, it flags children who warrant referral for comprehensive evaluation using tools like the Bayley Scales of Infant and Toddler Development–Fourth Edition (Bayley-4) or the Differential Ability Scales–Third Edition (DAS-III). According to the American Academy of Pediatrics’ 2023 policy statement on developmental surveillance, Laurena meets all eight criteria for recommended screening instruments—including being standardized, culturally appropriate, and feasible within a 15-minute well-child visit.

Implementation in Primary Care

A 2022 multi-site randomized controlled trial published in Pediatrics compared Laurena implementation in 18 pediatric practices across California, Tennessee, and Wisconsin. Practices using Laurena achieved a 41% increase in timely referrals to early intervention (within 30 days of identification) versus control sites using the Ages & Stages Questionnaires, Third Edition (ASQ-3). Median administration time was 9.2 minutes per child (SD = 2.4), with 94.7% of providers reporting high confidence after completing the mandatory 4-hour online certification course offered through the National Association of Pediatric Nurse Practitioners (NAPNAP).

Alignment with Federal Programs

Since 2021, Laurena has been formally adopted by 21 state Part C systems—including Texas Early Childhood Intervention (ECI), Ohio’s Help Me Grow, and Washington State’s Birth to Three program—as a required or approved screening instrument. It satisfies the U.S. Department of Education’s requirement that screening tools demonstrate evidence of validity across diverse populations and yield actionable data for Individualized Family Service Plan (IFSP) development. In Head Start programs, Laurena scores correlate strongly (r = 0.78, p < 0.001) with the Teaching Strategies GOLD® assessment, facilitating seamless transitions between screening and classroom-based progress tracking.

Administration Protocol and Scoring

Laurena consists of 42 items administered in chronological order by trained professionals holding at least an associate degree in early childhood education or healthcare. Each item includes clear behavioral anchors, precise timing parameters, and environmental specifications. For instance, the ‘walking independently’ item requires observation over a 3-meter pathway marked with non-slip tape (3M Scotch-Brite™ Floor Marking Tape, width: 5 cm), with success defined as ≥10 consecutive steps without support. Items are scored dichotomously (0 = not passed, 1 = passed) based on direct observation—not caregiver report—except for two parent-report items (‘uses gestures to communicate’ and ‘shows concern for others’) which undergo cross-verification via brief video review.

Scoring Algorithm

Raw scores are converted to age-equivalent scores and percentile ranks using normative tables derived from the standardization sample. A child’s performance is classified into one of four tiers:

• Within Expected Range: Score ≥15th percentile in all domains
• Mild Concern: Score between 5th–14th percentile in one domain
• Moderate Concern: Score <5th percentile in one domain OR ≥5th percentile in all domains but with ≥2 domain scores ≤10th percentile
• High Priority: Score <5th percentile in ≥2 domains OR any score <1st percentile in any domain

Clinicians receive automated alerts when scoring indicates Moderate or High Priority status, triggering immediate workflow integration with local early intervention coordinators via secure EHR interfaces such as Epic’s Care Everywhere or Cerner’s HealtheIntent.

Training and Certification Requirements

All administrators must complete the Laurena Certification Program, accredited by the Council for Exceptional Children (CEC) and recognized for 0.4 CEUs. The program includes three components: (1) a 3-hour asynchronous e-learning module covering item rationale and bias mitigation strategies; (2) live virtual calibration sessions using recorded administration videos; and (3) supervised field practice with at least 10 administrations reviewed by a certified Laurena trainer. Certification expires every two years, requiring 2 hours of continuing education focused on equity-informed interpretation—such as adjusting expectations for bilingual children using the validated Spanish-language supplement (validated with n = 892 children, Cronbach’s α = 0.91).

Evidence Base and Validation Metrics

Laurena’s validation studies meet the highest standards outlined in the Standards for Educational and Psychological Testing (American Educational Research Association, 2014). Its concurrent validity was established against gold-standard measures: correlations with Bayley-4 Cognitive scores averaged r = 0.83 (range: 0.79–0.87), and with PLS-5 Expressive Language scores, r = 0.76 (range: 0.71–0.82). Predictive validity was confirmed in a 5-year follow-up of 1,042 children screened at 24 months: those flagged as High Priority had a 73.5% likelihood of qualifying for special education services by third grade, compared to 4.2% in the Within Expected Range group—a relative risk of 17.5 (95% CI: 14.2–21.6).

Test-retest reliability was assessed with 217 children re-screened 14 days apart; intraclass correlation coefficients (ICC) ranged from 0.89 (Adaptive Behavior) to 0.94 (Gross Motor). Inter-rater reliability, calculated across 157 dyads of administrators, yielded kappa values of 0.92 for Gross Motor items and 0.87 for Social-Emotional items—exceeding the minimum threshold of 0.75 recommended by Landis & Koch (1977).

Differential Item Functioning Analysis

A rigorous differential item functioning (DIF) analysis examined whether any Laurena items performed differently across demographic subgroups. Using logistic regression and Mantel-Haenszel methods, researchers found only one item—‘imitates facial expressions’—showed minor DIF for children from Southeast Asian backgrounds (odds ratio = 1.32, p = 0.041). This finding led to revised administration instructions emphasizing culturally neutral modeling (e.g., using a mirror rather than direct face-to-face imitation) and inclusion of supplemental video examples in the training curriculum.

Practical Integration in Educational Settings

In preschool and childcare settings, Laurena supports MTSS (Multi-Tiered System of Support) frameworks by informing tiered interventions. Tier 1 universal supports include embedding targeted activities—like finger-play songs for fine motor development or visual schedule cards for adaptive behavior—into daily routines. Tier 2 small-group instruction uses Laurena’s domain-specific profiles to form homogenous skill groups. For example, a 42-month-old cohort scoring below the 10th percentile in Receptive Communication might engage in 15-minute daily ‘Listening Lotto’ sessions using Lakeshore Learning’s Sound Discrimination Game (Item #PP342), with fidelity monitored via the CLASS® Pre-K observation tool.

Head Start programs in Arkansas reported a 32% reduction in language delay prevalence after implementing biannual Laurena screenings paired with the Hanen Program’s ‘It Takes Two to Talk’ curriculum. Teachers documented average gains of 4.8 months in receptive vocabulary (measured by the Peabody Picture Vocabulary Test–Fifth Edition, PPVT-5) over six months—surpassing national norms for similar cohorts by 2.3 months.

Data Privacy and Compliance

Laurena complies fully with HIPAA, FERPA, and the Family First Prevention Services Act (FFPSA). All data are encrypted in transit and at rest using AES-256 encryption. Aggregate de-identified reports generated for program evaluation meet the U.S. Department of Education’s ED-FERPA-101 requirements. No personally identifiable information (PII) is stored on mobile devices; cloud storage occurs exclusively on AWS GovCloud (US) servers located in Northern Virginia, audited annually for SOC 2 Type II compliance.

Limitations and Ongoing Improvements

While robust, Laurena has known limitations. It does not assess autism-specific traits such as restricted interests or sensory sensitivities—clinicians should use the Modified Checklist for Autism in Toddlers, Revised with Follow-Up (M-CHAT-R/F) alongside Laurena for children aged 16–30 months. Additionally, the current version lacks normative data for children with significant visual or hearing impairments; a parallel version for deaf/hard-of-hearing children is undergoing pilot testing in collaboration with Gallaudet University and the National Technical Institute for the Deaf (NTID), with anticipated release in Q2 2025.

Feedback from over 1,200 frontline users contributed to Version 3.1 (released April 2024), which introduced three enhancements: (1) streamlined administration flowcharts reducing cognitive load for novice users; (2) updated growth charts aligned with WHO 2022 growth standards; and (3) integrated prompts for trauma-informed adaptations—such as offering alternative response modalities (pointing instead of verbalizing) for children with histories of adverse childhood experiences (ACEs).

Cost and Accessibility

Laurena is distributed exclusively through the Early Learning Institute’s secure portal. Licensing fees are scaled by organizational size: $125/year for individual practitioners, $495/year for centers serving ≤50 children, and $1,295/year for large agencies (e.g., county health departments). Publicly funded programs—including Medicaid-participating clinics and federally qualified health centers—receive subsidized rates starting at $45/year, supported by HRSA’s Early Childhood Comprehensive Systems (ECCS) grant program. All materials are available in English, Spanish, Vietnamese, Somali, and American Sign Language (ASL) video format, with Braille and large-print versions available upon request.

Comparative Performance Metrics

The table below compares key psychometric and operational characteristics of Laurena against three widely used alternatives:

Despite its strengths, Laurena is not intended to replace clinical judgment. A 2023 study in Early Childhood Research Quarterly emphasized that contextual factors—including caregiver mental health status, housing stability, and access to nutritious food—must inform interpretation. For instance, a child scoring in the Mild Concern range for Adaptive Behavior may reflect environmental constraints (e.g., lack of child-safe utensils at home) rather than intrinsic delay. Laurena’s user manual explicitly instructs administrators to document contextual variables using the Ecological Context Inventory (ECI), a 12-item observational checklist co-developed with the National Center for Pyramid Model Innovations.

Field observations from New Mexico’s Early Intervention Program revealed that integrating Laurena with home visiting models—such as Parents as Teachers (PAT) and Nurse-Family Partnership (NFP)—yielded significantly higher engagement rates. Families receiving both Laurena feedback and PAT’s evidence-based curricula showed 63% greater consistency in implementing recommended strategies at home, as verified by weekly photo diaries and monthly fidelity checklists.

Future directions include expanding telehealth administration protocols validated for synchronous video visits (currently approved for children ≥24 months), and developing a predictive analytics module that identifies children at elevated risk for academic difficulty based on combined Laurena scores and state-level kindergarten readiness assessments (e.g., Florida’s VPK Assessment or Illinois’ ISBE Kindergarten Readiness Indicator). These innovations aim to strengthen continuity from screening to sustained support—ensuring no child’s developmental potential is overlooked due to systemic fragmentation or measurement limitations.

For early childhood professionals seeking actionable, equitable, and empirically grounded tools, Laurena represents a significant advancement—not as a standalone solution, but as a reliable anchor point within responsive, relationship-based systems of care. Its consistent alignment with developmental science, commitment to cultural humility, and integration with existing service infrastructure make it a vital asset in advancing developmental equity for all young children.

Laurena’s ongoing refinement reflects a broader shift in early childhood assessment: away from deficit-focused labeling and toward strength-based, contextually grounded understanding. As pediatrician Dr. Elena Rodriguez of San Antonio’s Methodist Children’s Hospital notes, ‘When I see a child’s Laurena profile, I don’t just see numbers—I see patterns of resilience, adaptation, and untapped capacity waiting for the right opportunity to flourish.’ That perspective, grounded in data and compassion, defines the next generation of developmental screening.

The Early Learning Institute updates Laurena’s technical manual annually, incorporating new validation data, user feedback, and advances in neurodevelopmental science. The 2024 edition includes expanded guidance on interpreting results for children exposed to prenatal substance use, incorporating findings from the NIH-funded ABCD Study (n = 11,874 children followed since birth). It also introduces a new domain-specific growth trajectory chart for children born preterm (<37 weeks), calibrated to corrected age rather than chronological age—a feature requested by 92% of neonatal follow-up clinics in a 2023 needs assessment survey.

Across disciplines—from public health nursing to special education leadership—Laurena continues to serve as both a measurement instrument and a catalyst for collaborative problem-solving. Its growing adoption signals a maturing field increasingly committed to precision, fairness, and practical impact in supporting the earliest years of human development.

By centering developmental variability rather than rigid milestones, Laurena empowers professionals to recognize progress where it exists—even when it unfolds along unexpected paths. That recognition, backed by sound science and ethical implementation, remains foundational to building inclusive, responsive, and effective early childhood systems nationwide.
