You said his test was based on his grade, right? You want to see his score based on age not grade. You want to compare apples to apples. The numbers you have right now are lower and underestimate of your child.

I'll try to explain what I have learned here, but Dottie is the real expert.

Form A of the following achievement tests was administered:

Applied Problems / 28 / 2.8 / 2.3 - 3.5 / 98/90 / 83 / 114(109-120) / 8-4

AE (the very last numbers) is age equivalent. That means that an average child of that age would score the same like your child. For example he spells as well as an average 8 year 6 months old.

GE is grade equivalent. The same like above except you are talking about a child in such and such grade-month.

AE and GE will be the same regardless on the scoring (based on age versus grade)

SS (the number before AE) is a number which gives you an idea how he compares to other kids of his age or grade. It makes a huge difference if the tester used age or grade to calculate the numbers bellow.

100 is average (50%)
130 is 97% (meaning he scored better than 97% of kids of his age)
125 id 95%
120 is 90%

130 is usually considered gt but it's quite common that gt score bellow that.

I think you should contact the tester and see if you can get the SS numbers based on age instead of grade. The rest of the numbers will stay the same but the SS number will go up.

Dottie would probably tell you that some of the test show more than others when it comes to gt. Calculation is not as important as Applied Problems. Passage Comprehension is better indicator than Letter-Word Id
