The aim of the research was identification of Wechsler intelligence scale for children (WISC-IV) basic attributes based on Cattle- Horn- Carrol (CHC) narrow abilities by using generalized DINA (G-DINA) cognitive diagnostic model. The population of the research was all of Iranian primary school students which randomly 1222 students selected. We use Wechsler intelligence scale for children (WISC-IV) for gathering data. Results show that from the nearly 70 CHC narrow abilities, 9 narrow ability (visualization, induction, working memory, general verbal information, lexical knowledge, flexibility of closure, memory span, language development, general sequential reasoning) Identified as basic attribute of WISC-IV. Also from the constrained models, the LLM model based on Wald statistics was chosen. Additionally, most of student mastered in lexical knowledge and the lowest rate of mastering belongs to flexibility of closure. finally, the probability of guessing parameter in easy items was high and probability of slipping in difficult items was high.
