A standardized technique for measuring reading comprehension and vocabulary knowledge in people of different age groups, including children, adolescents and adults. The test consists of two main parts: a reading comprehension section, where participants read passages and answer questions, and a vocabulary section, which assesses knowledge of words. GMRT-4 is widely used in educational settings to assess students’ reading skills, assess their progress, and identify areas for improvement. It is also useful in research to assess literacy levels in different populations.
