I'm curious about the DAT curve

Members don't see this ad.

So I've been hearing mixed things... is it curved against everyone that took that same version of the DAT the same day as you OR simply people that took the same version of the DAT as you (same day or in the past).

Thanks in advance!

Is the DAT scored on a curve?


DAT performance is based on an ability referenced system and reported in standard scores. The test is not scored on a curve. Standard scores provide normative information about examinee knowledge and problem-solving skills allowing a direct comparison of an examinee’s ability with other examinee’s abilities


Go to page 5 of the attached file, that is what is stated by the ADA.

Hope this helps.

Hmm thanks for that. Here's something I found interesting,

"
Each test includes certain questions that play a special role within the testing program. Some questions enable us to place different forms of the test on a common measurement scale, thereby adjusting the forms for any differences in form difficulty level. Because of these questions, examinee scores have the same meaning regardless of the particular test form that was administered. Other questions on the test are experimental and are not scored. The data collected on unscored questions is used in later test construction processes, to ensure that these questions are appropriate before they are included among the scored items. "

So I'm assuming b/c the test has some baseline questions, it means that your score is compared against every version of the test? Did I interpret that correctly?

I have a friend at the ADA I will email tonight. I do not want to post any incorrect information or my interpretation, if it is not correct. The ADA baffles me at times.😕

I've heard the DAT is notoriously poor at standardization. Ie. the same percentile in different tests can yield very different scores.
