What Do My Child's Test Scores Mean?

I just received the results of my child’s testing scores for

Gifted and Talented services.  

What do they mean?

Here is a brief explanation of the information you received.

Your student took what is known as an ability test which is designed to "collectively assess the ability of students for each grade level". Their total score is "considered to be the best overall indicator of school learning ability."

To continue: "The School Ability Index is a normalized standard score with a mean of 100 and a standard deviation of 16. In the United States, in general approximately

2% of students will obtain SAIs above 132

14% of student will obtain SAIs ranging from 116 to 132

68% of students will obtain SAIs ranging from 68-115; and

2% of students will obtain SAIs below 68


In Tomball ISD, a student must first obtain an SAI of 126+ to continue testing.

If your child has continued in the testing process, the next scores you will see are related to the achievement portion of the testing. Your student needs to obtain a 95% or above in any of the following subjects in order to be considered for gifted and talented services in Tomball ISD: Reading, Math, Science, and Social Studies. Kindergarten students and first grade students who test in the fall are tested in Reading and Math.

As per the Gifted Plan for the State of Texas, we also collect information from other sources besides testing. We collect data from your child's teacher and from the parent. This information is compiled with the student's test scores and brought before school and district personnel who are certified to teach gifted and talented students in Texas. The committee works together to make the best placement decision for the student based on the information presented.
