TOGRA - Test of General Reasoning Ability

I have used one of my free administrations on PARiConnect to check out TOGRA.

TOGRA is a screen of reasoning and problem solving skills for ages 10 - 75, meant to minimize racial, gender and religious (?) bias. The website says that it was standardized on a 2010-Census-matched sample of 3,013 individuals, so the normative sample is very nice, as is the age range. There are two equivalent forms.

It is a timed, 16-minute multiple choice test. It is meant to measure verbal, nonverbal, and quantitative reasoning and the problems consist of: matrices, vocabulary (e.g.: which word does not belong, which word is the opposite of), and numerical patterns and equations (with relatively little working memory loading, as the client is allowed pen and paper). It is supposed to be supervised, so that the client does not use a calculator or internet.

I did a quick search for psychometric data:
internal consistency = .92
test-retest = 0.87

Not bad.

This is very much an assessment of reasoning, without speed of processing or working memory components. However, it looks like a very solid IQ screen, an excellent component of any computerised battery, or a way of quickly establishing GAI when focusing on a specific assessment issue.

Now, I better get back to writing reports.
