Introduction: Meeker’s cognitive abilities diagnostic test is used to measure the broad spectrum of children and adolescent’s abilities as well as adults. This test is based on a recognized multi-factorial model of intelligence developed by Guilford. This test has 26 subscales which measure specific abilities. It was standardized in America. In this research, the test was standardized among the 2nd to 5th grade elementary school students of Ilam. Materials & Methods: This descriptive study was used for current situation, while the test was standardized on 2nd to 5th grade elementary school students. Our statistical population was all the 2nd to 5th grade elementary school students of Ilam. The method of sampling was single periodic clustral sampling. 320 students participated in this research, whom escalated to 317 students due to dropout of 3 students. The samples were equally selected between the boys and girls. 80 male and female students were selected from each grade equally. The instrument of gathering data was Meeker’s test translated in Persian by the researchers. SPSS software was used for analyzing the data. Findings: The results of Chronbach’s alfa ranged from 0.7 to 0.86. The results of concurrent validity showed a significant relationship between the teacher’s assessment of student and Meeker’s subscale grades (p<.001). Furthermore, the result of factor analysis confirmed the factorial structure of Meeker’s test. Factorial loadings were over 0.3. The results of bar charts of Meeker’s subscales suggested that Meeker’s subscales distribution were normal. The results of percentile ranks of subscales were computed. Discussion & Conclusion: It is possible to identify the strength and weakness of elementary school students by Meeker’s test, and also design a suitable program for increasing such qualities. This is a basic step in education and makes it necessary to provide and apply some instruments such as Meeker’s test.
