Final Answer :
True
Explanation :
A national standardized testing company can report a student's percentile rank, which represents their relative standing compared to other test-takers, without sharing the mean or standard deviation of the exam scores. Percentile rank indicates the percentage of test-takers who scored lower than the individual, but it does not require knowledge of the overall shape or spread of the distribution.
