Full-length IQ test needed for initial evaluation for special ed?
A psychologist recently administered an abbreviated IQ test to determine if my child met eligibility criteria for special education under a specific learning disability. I thought initial evals always had to include a full-length IQ test, although re-evals could utilize abbreviated test scores
It is very common for professionals to choose subtests they feel will give a representative picture of the disorder being tested for. Some subtests aren’t necessary for every child, and administering them makes an eval unnecessarily long, which can can skew results by fatiguing the child and his/her attention span.
