At what age is the TDSC developmental assessment used for a child?
The Trivandrum Developmental Screening Chart (TDSC) is a brief, India-developed screening tool used for children from birth up to about 2 years of age (0–24 months). It is a screening tool, not a diagnosis — it checks expected early milestones against a child's age and flags when a closer developmental assessment may help. The 0–2 year window matters most because the brain grows fastest then, and timely support makes a real difference.
Read the answer AnswerTrivandrum Developmental Screening Chart (TDSC) explained
The Trivandrum Developmental Screening Chart (TDSC) is a quick, low-cost developmental screening tool developed in India to flag possible developmental delay in young children. It is a screen, not a diagnosis: a vertical line is drawn at the child's age and milestones the line crosses are checked. It assesses broad early development — gross motor, fine motor, language and social/self-help skills — and is designed for easy use by health workers in community and clinic settings. A positive screen is an invitation to a fuller clinician-led assessment, not a label.

How TDSC compares with the AbilityScore assessment
The TDSC is a quick, low-cost screening checklist designed to flag children who may need a closer look, often used in community settings by frontline workers. The AbilityScore® is a deeper, clinician-administered structured assessment that maps a child's abilities across domains to guide a personalised therapy plan and measure progress. They are complementary: a screen asks 'should we look closer?', while the AbilityScore® answers 'what exactly does this child need?' Any clinical assessment or diagnosis is formed only at a Pinnacle Blooms Network centre under a qualified clinician.
Read the answer AnswerShould my child have a TDSC assessment, and what does it involve?
The TDSC is a quick, India-validated developmental screen — not a diagnosis — that checks whether your child's milestones are on track in a few minutes. A 'refer' result simply means a fuller, qualified assessment is sensible. It is a good first step if you have a gentle worry or want a routine check, and only a Pinnacle clinician can confirm what any result means.
Read the answer AnswerTDSC: Indications, Strengths and Limits in Early Childhood
The TDSC is a rapid, Indian-validated developmental screen for children from birth to ~2 years (extended to ~6 years), suited to primary-care, anganwadi and field settings. Its strengths are speed, local norms and minimal training; its limits are that it is single-axis, non-diagnostic and not domain-specific. A positive screen should trigger structured assessment and referral, never a label.
