Some IAS requirements (paraphrased by me):

Section II: Critical Items

If any of these items apply to the student in question, whole-grade acceleration is not recommended.

*The student's ability (measured by IQ) is less than one standard deviation above the mean.
*The student would be accelerated into the same grade (or a higher grade than) a sibling.
*The student presently has a sibling in the same grade.
*The student indicates that he/she does not want to be whole-grade accelerated.

Section IV: Assessment of Ability

The student's overall IQ score was:

Between one and two standard deviations above the mean (115-129) >>> 2 points
Between two and three standard deviations above the mean (130-144) >>> 4 points
Three or more standard deviations above the mean (145-above) >>> 6 points

Section V: Assessment of Aptitude

IBTS/EXPLORE/ACT/SAT

On an above-level test (compared to students in the above-level grade), the student's scores were:

At or below the 49th percentile >>> 0 points
Between the 50th and 74th percentile >>> 1 point
At or above the 75th percentile >>> 2 points

Consider each section (English, Math, Reading, Science Reasoning, One other) separately and total all points (for a maximum of 8).

Or:

PLUS/SAT/SCAT/CTP-IV

At or below 49th percentile >>> 0 points
Between the 50th and 74th percentiles >>> 2 points
At or above the 75th percentile >>> 4 points

Consider Verbal and Quantitative sections separately and total the points.

Section VI: Assessment of Achievement

On a grade-level test, the student's scores were:

At or below the 89th percentile >>> 0 points
Between the 90th and 94th percentiles >>> 1 point
At or above the 95th percentile >>> 2 points

Consider each category (Vocabulary, Total Reading, Total Math, Total Language, One other) separately and total the points (for a maximum of 8).

AAAA Subtotal = sum of totals from sections IV,V,VI.
If AAAA Subtotal < 10, whole-grade acceleration is not recommended.
If AAAA Subtotal >=10, continue with the rest of the IAS.
