What are your reasons for seeking a two-year skip?

Acceleration is a frequent topic on the forums and is not based on IQ alone.

Are you familiar with the Iowa Acceleration Scale (IAS)? It is described here on Hoagies' Gifted Education Page, and is considered the gold standard for evaluating evidence for/against a full-grade skip at a given point in time.

The IAS is in its 3rd edition (2009) and is therefore sometimes called IAS-3.

There are three parts to the IAS:
1) Manual (re-usable paperback with process description, essays, examples)
2) Form (one form is completed for each child, each time an acceleration is considered)
3) Summary and Planning Record (one summary and planning record is completed for each child, each time an acceleration is considered)

The IAS is described on the website of the Acceleration Institute and is available from Great Potential Press. If your school is not aware of the IAS, you may wish to share this information with them.

The IAS recommends tests which measure student ability, aptitude, and achievement. This list is a roundup of these tests:

Ability
Most recent Wechsler or Binet, Woodcock-Johnson... or CogAT

Aptitude
Above-level tests such as ITBS, EXPLORE, or ACT

Achievement
Wechsler Individual Achievement Test (WIAT) or Woodcock-Johnson Tests of Achievement (WJ-ACH).

Have you read other discussion threads which list pros/cons of acceleration? This post, in a thread called Considering grade skip, contains a roundup of acceleration discussion threads, which you may wish to explore.
