Chronological Age in Occupational Therapy
Occupational therapists rely on accurate chronological age calculation to select developmentally appropriate assessments, interpret norm-referenced scores, and establish realistic treatment goals. Precise age computation ensures valid evaluation of pediatric clients across all functional domains.
Role of Age in OT Assessment
Chronological age serves as the foundational metric in pediatric occupational therapy. Every standardized assessment used by OTs requires the child's exact age at the time of evaluation to derive valid standard scores and percentile ranks.
Our chronological age calculator provides the precise age computation needed for OT documentation. For premature infants, use our adjusted age calculator to account for early birth.
Common OT Assessments Requiring Age
- PDMS-2 — Peabody Developmental Motor Scales
- BOT-2 — Bruininks-Oseretsky Test of Motor Proficiency
- Sensory Profile-2 — Dunn Sensory Processing Assessment
- SPM — Sensory Processing Measure
