The research tools were a selected test of Nonverbal Intelligence, Third Edition<br />(TONI-3) and The Colored Progressive Matrices (CPM).<br />Results: Showed that the TONI-3 test had†convergent validity to CPM test at a moderately high level (r=0.488) and had construct validity that was more capable of categorizing intelligence<br />into extreme groups than CPM (Colored Progressive Matrices Test). Regarding practicality, the comparison between group and individual testing indicated that TONI-3 had higher accuracy when applied with individual testing. Therefore, in practicality, TONI-3 was less practical than CPM because TONI-3 was only able to be given individually. Besides, the study of comparison of composite scores as classified based on gender and age. No gender difference but having<br />a trend to increase when age increased.<br />Conclusion: TONI - 3 was not appropriate for use by an examiner who had never been trained before because TONI-3 had some certain conditions for practice. However, TONI-3 could be<br />considered as a screening test that the examiner could use other supplement standardized intelligence testing instruments or to confirm the results of other tests. ER -
