Since this year the only score that counts for the pool is the composite (which is based on "Grade Scores" younger kids are at a disadvantage.  When you compare "Age Scores" for oldest to youngest there is about a 10 point swing.

As the pool size gets smaller, the reliability goes down which is the problem with the "local scores".

When using non-age adjusted scores there is a fairly strong bias (about 10 percentile swing (or .4 standard deviation) against the younger since they have had less experience in school and life.

You are wrong on several levels. The composite is NOT based on "grade scores." Pull out your test results. It clearly lists the three category scores as well as the composite under "standard age score." The score the committee considers is in the age score section. Also, a younger child in the grade has no more experience in school than an older child. A younger student has been in school exactly the same number of years as an older student and has been taught exactly the same subjects. A child who turns eight in October should be graded on the same level as a child who turns eight in November. A child who turns eight in October should not be expected to know as much as a 3rd grader. A 3rd grader has had more instruction and experience than a 2nd grader. An older 2nd grader has had the same exact amount of instruction and experience as another 2nd grader. [/quote]

It's not just about instruction received and knowledge retained.  It's about the child's development.  A child who is born in September (and went to school on time) could be 15 mos. younger than a child who was born in June/July and red-shirted.  Mental development and logical reasoning changes as a child ages.  It can be a significant difference that has nothing to do with the number of years a child has attended school.  An older child has also had an extra year of life experience and "education" from his/her parents (i.e. explaining how things work and such).  IMO (and apparently in the opinion of quantitative and developmental psychologists and neuropsychologists),  having the benefit of an extra year of living and brain development DOES provide an advantage.... and the way to account for that is by age-norming the scores so younger kids are not DIS-advantaged.

If those younger students need to be graded on a curve to give them an advantage, they are not ready for the AAP program. All second graders should be scored on the same scale. They will be the attending class TOGETHER. This affects kids who went to school on-time (October and fall months) too. [/quote]
