To examine the reliability of the Bruininks-Oseretsky Test of Motor Proficiency-Long Form (BOTMP-LF), approximately 40 therapists completed a questionnaire on the administration and scoring of this test (72% response rate). A large degree of inconsistency between therapists was found. This prompted a study of interrater reliability of six therapists who received rigorous training on the BOTMP-LF. Results indicated that consistency of scoring between testers was statistically high for the battery, composite, and subtest scores. However, item-by-item agreement was low for many items, and agreement between raters on their diagnosis of the children as having motor problems was only fair to good. There was no difference in interrater reliability of the test for children with and without learning, attentional, or motor coordination problems. Some limitations of the BOTMP-LF are apparent from these studies.
