This is a normative study to investigate the transferability of norms to Filipino students. More than 2,700 Filipino sixth graders were sampled across the country and administered the Naglieri Nonverbal Ability Test (NNAT). Scores were then compared to the US normative sample. The results showed no significant difference in mean scores. However, further analysis revealed that the proportion of students within each stanine equivalent does not correspond with the expected values as presented in the US norms. As such, it is not valid to transfer the US norms directly for Filipino students without any modification. Based on the results, a new stanine equivalence tables for NNAT scores were developed for sixth grade Filipino students. A significant difference in mean scores was also found among the three geographic regions. Although the difference is relatively small, separate regional norms were also developed for the Filipino students.
