Item Difficulty in Item Analysis of the Wechsler Preschool and Primary Scale of Intelligence (WPPSI-IV) – Using Item Response Theory Approach (Published)
Measurement theories have gone through a lot of evolution; one of which is Item Response Theory, which is an improvement on the Classical Test Theory (CTT). This study looked into the difficulty status or difficulty parameter of the Wechsler Preschool and Primary Scale of Intelligence (WPPSI-IV). 512 subjects were randomly selected and administered the WPPSI-IV instrument. Findings from the study show that 241 items were good, 6 were easy, and 23 were difficult. It was therefore concluded that some items in the WPPSI-IV are adaptable and adoptable for use to measure children’s intelligence, age 7. It was recommended that WPPSI-IV is good enough and should therefore be administered to measure children’s intelligence approximately age 7. Also, it was recommended that the difficult and easy items could be replaced with better ones.

The purpose of this study was to compare the academic achievement and intelligence level of Secondary School students of science, management, and education streams to identify the enrollment trend of students in teacher education in Nepal. Mean score of grade point averages and intelligence test of science stream students was greater than management stream students and average scores of management stream students were greater than education stream students. F-test revealed that there was significant difference among the mean scores of science, management, and education stream students at significance level α = .01.Results show that the students with higher academic achievement and intelligence level are enrolling in science stream, average are in management stream and with low academic achievement and intelligence are in education stream, i.e., teacher education.
