A score is calculated for each of the 13 individual scales in the following way:
Scale points 1?3
If a child attains scale points 1, 2 or 3, their score is recorded
accordingly as 1, 2 or 3 scale points.
Scale points 4?8
A child can attain up to five scale points in this grouping.
For each scale point achieved, 1 is added to the base score of 3
(carried over from scale points 1?3 above) to give a total score.
For example, if a child attained scale point 4, scale point 6 and scale
point 8 on a particular scale, he or she would add 3 to their base score
of 3 to create a total score of 6.
Scale point 9
A child attaining scale point 9 will have attained all scale points 1?8 on
a particular scale and their total score will be recorded as 9 points.
reaching the early learning goals, means your child will have scored 8, stepping stones would correspond to a 6 or a 7. Children hwo are already capable of national curriculum type stuff would score 9
average is to be somewhere between early learning goals and the top of the stepping stone
