Abstract EN

The research aims to know the effect of different individuals' ability level on differential performance of Master Brian's nonverbal mental ability test consisting of (60) items distributed by ten paragraphs and on six components which are (1.

Symmetry or symmetry 2.

The matrix 3.

Exclusion of the strange shape 4.

Similarity) 5.

The code symbols 6.

The string or strings).

The current research was limited to middle school students in Baghdad and for the morning study (2019-2020).

To achieve the objectives of the research, the test was applied to a sample of (600) middle school students in Baghdad in a random, stratified manner, and then the assumptions of the response theory of the singular were verified (onedimensional positional independence, the characteristic curve of the paragraph, the test is not a speed test).

The results showed the following: Matching (55) items of the Master Brian test vocabulary for the two-parameter model.

The results showed that 10.90% of items and that for individuals' sample as a whole and 18.18% for individuals with low ability and 16.36% for individuals with high ability with differential performance according to the single response theory and the two-parameter model.

The absence of statistically significant differences in the percentage of items with differential performance according to the single response theory and the twoteacher model according to the ability level, where the comparison was made between the sample as a whole and the higher ability level and the lower ability level two by two.

There are no statistically significant differences in the value of differential performance according to the singular response theory and the two-teacher model and its average level of ability
