My son was tested when he was 6 years old and in the 1st grade. He received a score of 154 on the RIAS. He is now 14 and in the 8th grade and would like to be tested again. How often should students be tested? His reasoning is, well, he was 6. He cannot remember taking it, so he wonders how seriously he took it and how accurate the result is. The original test was taken at his elementary school. If we test again, can I request that through his middle school? What other testing options do we have? Thank you!
