The TMA instrument is a mental ability test that helps measure an individual's ability to learn new skills quickly, adjust to new situations, understand complex or subtle relationships, and be flexible in thinking. The TMA test helps assess an individual’s capacity to learn and understand the requirements of the job. The test consists of two scales:

Quantitative. Items consist of arithmetic reasoning and number-series problems.

Linguistic. Items consist of same-opposite word meanings and definitions.

Norms are also available for other positions. Educational norms are listed for 9th-,10th-, 11th- and 12th-grade students by linguistic, quantitative and total score.
