Comparison of scales used on Commtap

Three developmental scales are currently used on Commtap - age ranges in the Early Years Foundation Stage Curriculum, National Curriculum levels and the P-Scales which lead up to this, and the TAP scale. This page is a guide to how these levels roughly equate in terms of typical developmental level. Note that age ranges are used in the EYFS curriculum - this reflects the variation between typcially developing children in terms of when they acquire skills and the order in which they may acquire them. The other scales do not reflect this variation.

P-Scales/National Curriculum level	TAP level	Approx. developmental age (Sheridan 1975)	Developmental age range given in the EYFS curriculum by which all skills indicated in Sheridan (1975) and the corresponding P-level should have been achieved.
