Consequently, students can take different versions of the same test. These tests are called computerized adaptive tests or CATs. This digest offers some insights into the advantages and disadvantages of CATs. In general, computerized testing greatly increases the flexibility of test management. Neither answer sheets nor trained test administrators are needed.

Self-paced administration also offers extra time for students who need it, potentially reducing one source of test anxiety. Test security is increased because hardcopy test booklets are never compromised. Computerized testing also offers a number of options for timing and formatting.
