Changes in selection criteria have meant that children are being provided with cochlear implants (CI) at increasingly younger ages. However, there is a paucity of measures that are appropriate for testing complex listening skills--most tests are too cognitively complex for such young children. The Common Objects Token (COT) Test was developed as a complex closed-set test for children with profound hearing losses. This test was assessed for its usefulness in assessing children with cochlear implants. The test was administered to 20 implanted children over a period of two months. Results indicated that some subtests were equal and there was not a hierarchical subtest order. Based on these findings, the test was modified and then re-assessed on 85 children. Outcomes showed that all subtests assessed the same construct. Two subtests were able to predict the total score of the COT test. The test was modified to include two levels, one with easier tests suitable for younger children, and a shorter, quicker version for instances where there may be attention span or time constraints. Outcomes showed that the test may be suitable for children aged three and above and that children with less than two years of CI experience are able to perform on the test. The results of this testing indicated that the COT test is a useful addition to the test battery for assessing young implanted children. (Contains 4 tables and 7 figures.)
