This is from the guidance our LEA send us to fill in the transitions for school ( I do work ina nursery but this should be helpful to anyone delivering the EYFS)
Completion of the Developmental Age Bands
Summary Judgement
"Development Matters might be used by Early Years settings throughout the EYFS as a guide to making best-fit judgements about whether a child is showing typical development for their age, may be at risk of delay or is ahead for their age. Summative assessment supports information sharing with parents, colleagues and other settings." Development Matters p.3
The definitions below may be used by practitioners to identify a "best fit" judgement for each child to enhance the quality of information sharing and progress indicators. To arrive at a summative judgement, it is advised that the practitioner should identify the main age/stage band evidenced by a child's learning and development in the relevant aspect, then consider the relevant degree of security within the selected band.
NB: There can be no definitive criteria for what might differentiate levels of security within an age band. The bands overlap because these are not fixed age boundaries, but suggest a typical range of development. Children develop at their own rates and in their own ways; therefore, a child may demonstrate some of the development statements in more than one age/stage band simultaneously.
Entering (E) starting to demonstrate some of the features of this age band
Developing (D) typically operating securely within this age band, although not necessarily consistent
Confident (C) typical behaviour which is thoroughly embedded
