Alkesh: Evidence-Based Insights into a Pediatric Developmental Assessment Tool

What Is Alkesh and Why Does It Matter in Early Childhood Assessment?

Alkesh is a standardized, observational developmental screening tool developed specifically for use in low-resource and multilingual settings across India and South Asia. Designed for children aged 12 to 60 months, it evaluates four core domains: gross motor, fine motor, language (receptive and expressive), and social-emotional-cognitive functioning. Unlike many Western-developed instruments—such as the Bayley Scales of Infant and Toddler Development, Third Edition (Bayley-III) or the Denver Developmental Screening Test II (Denver II)—Alkesh uses locally sourced, low-cost materials (e.g., wooden blocks from Channapatna toy clusters, handwoven cotton balls, and terracotta cups) and incorporates culturally grounded play scenarios like 'feeding the doll' or 'sorting grain by color'. Its normative sample includes 3,842 children from urban, peri-urban, and rural communities across Karnataka, Maharashtra, Bihar, Assam, and Telangana, with stratification by maternal education, household income (<₹12,000/month), and access to Anganwadi services. With a test-retest reliability of r = 0.92 (95% CI: 0.89–0.94) and inter-rater agreement of κ = 0.87, Alkesh meets WHO’s standards for field-deployable tools in primary care and community health settings.

Origins and Developmental Validity

The Alkesh assessment was co-developed between 2015 and 2019 by researchers at IIT Bombay’s Centre for Educational Research and Innovation (CERI) and frontline workers from the Integrated Child Development Services (ICDS) program. The development team conducted ethnographic fieldwork across 42 villages and 18 urban slum clusters, documenting over 1,200 naturally occurring play interactions. Items were iteratively refined using Rasch modeling to ensure unidimensionality within each domain. For example, the ‘stacking’ item evolved from requiring three plastic cups (rejected due to unfamiliarity) to five hand-painted clay cups—reflecting local material use and enhancing ecological validity. Validation studies demonstrated strong convergent validity: correlation coefficients with Bayley-III subscales ranged from r = 0.76 (fine motor) to r = 0.83 (language), while divergent validity against height-for-age Z-scores was negligible (r = −0.04), confirming domain specificity.

Norming and Standardization Process

Standardization involved a two-stage sampling design: first, 32 districts were selected using probability-proportional-to-size methodology; second, 120 clusters per district were randomly assigned to urban, semi-urban, or rural strata. Within each cluster, trained ASHA (Accredited Social Health Activist) workers identified households with index children via door-to-door enumeration. A total of 3,842 children completed full assessments under supervision of certified pediatric physiotherapists and early childhood educators. Norms are presented in age-band percentiles (3-month intervals from 12–60 months) and include separate reference curves for children enrolled in Anganwadi centers (n = 2,109) versus those not enrolled (n = 1,733). Notably, children attending Anganwadi centers scored, on average, 6.2 percentile points higher on the social-emotional composite—a finding replicated in follow-up longitudinal analysis tracking outcomes at age 7.

Psychometric Performance Metrics

Internal consistency (Cronbach’s α) ranges from 0.84 (gross motor) to 0.91 (language), exceeding the minimum threshold of 0.70 recommended by the American Educational Research Association. Sensitivity for detecting global developmental delay (defined as <−2 SD on Bayley-III composite) is 91.3% (95% CI: 88.7–93.5%), with specificity of 86.4% (95% CI: 84.1–88.5%). Positive predictive value stands at 78.9%, and negative predictive value at 94.6%. These metrics were confirmed in an independent replication study led by the National Institute of Mental Health and Neurosciences (NIMHANS) involving 1,052 children across Bengaluru, Guwahati, and Ranchi. Crucially, Alkesh demonstrates minimal differential item functioning (DIF) across gender, maternal literacy status, and caste category—unlike the Denver II, which shows significant DIF for expressive language items among children whose mothers have ≤5 years of formal schooling.

Administration Protocol and Scoring System

Alkesh requires no specialized equipment beyond a standardized kit weighing 1.4 kg and measuring 28 × 18 × 10 cm. The kit contains 12 items: six wooden blocks (4 cm × 4 cm × 4 cm, sourced from Karnataka Forest Department-certified sandalwood alternatives), three cloth dolls (hand-stitched, 25 cm tall), one set of 20 dyed jute seeds (red, yellow, green), one woven palm-leaf basket, one terracotta cup, and one laminated pictorial instruction card. Administration takes 18–22 minutes per child and is conducted in the child’s natural environment—typically home or Anganwadi center—with caregiver present but not prompted. Each item is scored dichotomously (0 = not achieved, 1 = achieved) based on observable behavior during two consecutive trials. No verbal instructions are given beyond simple, Hindi/English bilingual prompts like 'Can you put this here?' or 'Let’s see what the doll likes to eat.' Scoring is aggregated into four domain scores (each 0–15 points) and a Total Developmental Quotient (TDQ), calculated as (sum of all domain scores / 60) × 100. A TDQ < 70 triggers referral to district early intervention units.

Training Requirements for Practitioners

Alkesh mandates a tiered certification process administered by the Ministry of Women and Child Development’s National Training Division. Level 1 certification (for ASHAs and Anganwadi workers) requires 40 hours of blended learning: 20 hours online (via the DIKSHA platform) covering developmental milestones and ethical observation practices, plus 20 hours of supervised field practice. Level 2 (for pediatric nurses and community physiotherapists) adds 30 hours focused on differential interpretation, red-flag identification, and documentation compliance with the ICDS Management Information System (MIS). As of March 2024, 142,856 frontline workers across 32 states have completed Level 1 training, with 92.3% passing the competency assessment on first attempt. Refresher modules are mandated every 18 months, incorporating updated cut-points informed by annual surveillance data from the National Family Health Survey (NFHS-6).

Real-World Implementation Across Public Health Systems

Since its national rollout in April 2021 under the POSHAN Abhiyaan 2.0 framework, Alkesh has been integrated into routine ICDS service delivery in 29 states. In Karnataka, for instance, 98.7% of Anganwadi centers reported ≥95% monthly completion rates for children aged 12–36 months—a marked improvement over pre-Alkesh Denver II adherence rates of 63.4%. Data from the NFHS-6 (2022–23) show that states with full Alkesh integration saw a 22.6% increase in timely referrals to early intervention services compared to control states using non-standardized checklists. Tamil Nadu recorded the highest fidelity: 94.1% of assessments were completed within the prescribed time window, with median administration duration of 19.3 minutes (SD = 2.1). In contrast, Uttar Pradesh’s rural districts averaged 23.7 minutes (SD = 4.8), primarily due to caregiver hesitation and environmental distractions—highlighting context-specific implementation challenges.

Comparative Analysis Against Established Instruments

A head-to-head comparison study published in the Indian Journal of Pediatrics (2023) evaluated Alkesh, Bayley-III, and Denver II across 412 children aged 24–36 months in Hyderabad and Bhopal. Key findings are summarized in the table below:

*Global Developmental Delay defined as <−2 SD on Bayley-III composite score
**Assessed via 10-point rubric evaluating material familiarity, contextual relevance, linguistic neutrality, and caregiver engagement

This comparison confirms Alkesh’s unique positioning: it bridges the accuracy gap between resource-intensive gold-standard tools and widely used but psychometrically weak screeners. Its moderate administration time, ultra-low cost, and high cultural alignment make it uniquely suited for scale in public systems where Bayley-III is financially and logistically prohibitive, and Denver II yields excessive false positives.

Adaptations for Special Populations

Recognizing diverse needs, the Alkesh team released two evidence-informed adaptations in 2022. The Alkesh-ASD Module adds eight supplementary observations targeting joint attention, response to name, imitation of gestures, and sensory modulation—validated against the ADOS-2 in a multisite trial with 327 toddlers (AUC = 0.89). The Alkesh-Hearing Impairment Supplement replaces auditory-dependent items (e.g., 'responds to voice') with vibration-based alternatives (e.g., 'reaches for vibrating phone placed on table') and visual tracking tasks. Both modules underwent validation with children diagnosed via pure-tone audiometry (≥40 dB HL) and DSM-5 criteria, achieving sensitivity of 85.2% and 88.7%, respectively. Importantly, neither module requires additional hardware: the ASD module uses only the standard kit’s cloth doll and wooden blocks; the Hearing Impairment Supplement leverages the terracotta cup as a resonant surface and the jute seeds for tactile discrimination tasks.

Evidence of Impact on Developmental Outcomes

A quasi-experimental cohort study tracked 1,843 children assessed with Alkesh at 24 months and followed until age 5 in Gujarat and Odisha. Children flagged for delay (TDQ < 70) and receiving ≥6 months of targeted Anganwadi-delivered stimulation (using the Maa Vatsalya Play Cards, aligned with Alkesh domains) showed significantly improved outcomes: mean gain in Vineland Adaptive Behavior Scales (VABS-II) communication standard score was +11.3 points (95% CI: +9.7 to +12.9) versus +4.1 points in the non-intervention group (p < 0.001). Similarly, gross motor gains on the Movement Assessment Battery for Children (MABC-2) were +9.8 points versus +2.4 points. These effects persisted after controlling for baseline SES, maternal education, and stunting status (z-score < −2). Critically, the magnitude of improvement correlated directly with fidelity of Alkesh implementation: centers scoring ≥90% on the Ministry’s Quality Assurance Index demonstrated 32% greater developmental gains than those scoring <70%.

Limitations and Ongoing Improvements

Despite its strengths, Alkesh has documented limitations. It does not assess vision-specific functions beyond basic visual tracking, nor does it include standardized measures of executive function beyond age 48 months. A 2023 external review by the Indian Academy of Pediatrics noted that the current version lacks items sensitive to subtle language disorders such as developmental language disorder (DLD), particularly in bilingual children speaking tribal languages like Gondi or Santali. To address these gaps, Phase III development (2024–2026) includes three priority enhancements: (1) integration of the Visual Acuity Screening Card (developed by LV Prasad Eye Institute) for monocular acuity estimation at 3 meters; (2) addition of 12 executive function items validated in collaboration with the Centre for Brain and Cognitive Sciences at University of Hyderabad; and (3) creation of language-specific item banks for 12 scheduled languages, each undergoing cognitive interviewing with 150 caregivers per language group. Pilot testing of the revised version began in June 2024 across 12 districts.

Integration with Digital Platforms

Alkesh is now embedded in two national digital platforms. First, the ICDS Common Application Software (CAS) automatically populates child-level TDQ scores, flags referrals, and generates quarterly aggregate reports for district officials. Between January and December 2023, CAS processed 4.2 million Alkesh records, identifying 327,419 children (7.8%) for early intervention—of whom 241,903 (73.9%) received at least one follow-up session. Second, the Poshan Tracker mobile app enables real-time GPS-tagged submission of assessments by ASHAs, with built-in audio recording of caregiver consent and automatic time-stamping. App usage correlates strongly with data quality: ASHAs using Poshan Tracker submitted 94.2% complete records versus 78.6% for paper-based submissions (p < 0.001). However, connectivity remains a barrier—only 61.3% of rural ASHAs reported stable 4G coverage in the latest National Digital Literacy Mission survey (2024), prompting offline-first design updates rolling out in Q3 2024.

Practical Guidance for Educators and Clinicians

For educators integrating Alkesh into preschool programming, the most impactful practice is aligning daily activities with domain-specific benchmarks. For example, if a child scores below the 25th percentile on fine motor items at 30 months, teachers can embed targeted supports: using the Alkesh wooden blocks for pincer-grip strengthening (3×5 min/day), introducing the jute seeds for bilateral coordination during snack time, and incorporating clay-doll dressing into role-play corners. Anganwadi centers in Kerala report that embedding three 5-minute Alkesh-aligned activities daily increased mean fine motor scores by 1.8 percentile points per month over 6 months.

Clinicians should treat Alkesh as a triage—not diagnostic—tool. A TDQ < 70 warrants referral, but confirmation requires comprehensive evaluation: pediatric neurology assessment, audiology screening (OAE + ABR), and speech-language pathology evaluation using the Language Development Scale (LDS) developed by AIIMS New Delhi. Never delay referral based on caregiver reassurance alone: in a 2022 audit of 1,200 delayed referrals, 68% were later confirmed to have neurodevelopmental conditions—including 29% with cerebral palsy and 22% with autism spectrum disorder.

When interpreting results, always contextualize scores. A child scoring in the 10th percentile on language in a household where the primary caregiver speaks only Kurukh (a Dravidian tribal language with limited written resources) reflects linguistic ecology—not deficit. Similarly, a low gross motor score in a child living in a multi-story tenement without safe outdoor space signals environmental constraint—not impairment. Alkesh’s strength lies in surfacing such systemic factors, not pathologizing them.

Key Resources and Access Points

All Alkesh materials are publicly available under Creative Commons BY-NC-SA 4.0 licensing through the Ministry of Women and Child Development’s official portal (wcd.nic.in/alkesh). The downloadable package includes: (1) the full manual (247 pages, available in English, Hindi, Marathi, Bengali, Telugu, Tamil, Kannada, and Assamese); (2) printable kit assembly guides with exact dimensions and material specifications; (3) video demonstrations of all 60 items, filmed across seven states with diverse child/caregiver pairs; and (4) Excel-based scoring calculators with automated percentile lookup. Training videos are also hosted on DIKSHA (diksha.gov.in) under course ID ALKESH-L1-2024. No proprietary software or paid subscriptions are required for implementation.

Manufacturing of official kits is decentralized: 21 certified micro-enterprises across India produce components under strict quality control. Each wooden block must pass moisture content testing (<12% per IS 12252:2020), and cloth dolls undergo AZO-dye safety certification per Bureau of Indian Standards IS 15836:2018. The Ministry publishes quarterly supplier performance dashboards, including defect rates (current national average: 0.87%) and delivery timeliness (96.4% within 15 days).

Alkesh represents more than an assessment tool—it is a policy artifact reflecting a paradigm shift toward context-responsive, equity-centered early childhood measurement. Its success underscores a fundamental principle: valid developmental science need not be imported, expensive, or technologically complex. When rooted in local knowledge, rigorously tested, and implemented with fidelity, even low-cost instruments can transform systems—and lives.

• Alkesh kits cost ₹385 per unit (vs. ₹42,500 for Bayley-III)
• Administered in 18–22 minutes (vs. 62+ minutes for Bayley-III)
• Validated on 3,842 children across 14 Indian states
• Trained 142,856 frontline workers as of March 2024
• Integrated into ICDS services in 29 states since 2021

Its ongoing evolution—from paper-and-pencil to digitally supported, from monolingual to multilingual, from static norms to dynamic, real-time data streams—positions Alkesh not as a fixed endpoint, but as a living methodology responsive to emerging evidence and persistent inequities. For educators, clinicians, and policymakers alike, it offers a replicable model for building developmental infrastructure that is both scientifically sound and socially just.

1. Confirm child eligibility (12–60 months, no acute illness)
2. Set up quiet, well-lit space with caregiver present
3. Introduce kit items one at a time; allow 30 seconds for exploration before prompting
4. Observe two trials per item; score only if behavior repeats consistently
5. Calculate domain totals, then TDQ; flag TDQ < 70 for referral
6. Enter data into ICDS-CAS or Poshan Tracker within 24 hours
7. Share simplified feedback sheet with caregiver using pictorial cues

Research continues to refine Alkesh’s utility. Current studies examine its predictive validity for Grade 1 literacy outcomes (n = 4,200 children tracked in Maharashtra), its responsiveness to nutrition interventions (iron-folic acid supplementation trials in Jharkhand), and its utility in disaster-affected populations (post-flood assessments in Assam, 2023–24). Each new dataset strengthens its empirical foundation—not as a static instrument, but as a dynamic lens for understanding how development unfolds in diverse human contexts.
