['To assess the inter-tester and intra-tester reliability of the tuck jump test.', 'Repeated measures.', 'University Human Performance laboratory.', 'Five male and 5 female athletes undertook the Tuck jump test which was then assessed by two independent assessors.', 'Score from the video assessment of the tuck jump test by two independent assessors on two separate occasions.', 'Average percentage of exact agreement (PEA) between the two testers across all scoring criteria for all subjects was 93% (range 80-100%). Both testers were in absolute 100% agreement in 5 out of 10 subjects for all of the scoring criteria. The kappa measure of agreement was k\xa0=\xa00.88 which is very good/excellent. The intra-tester PEA ranged 87.2%-100%, with kappa values of k\xa0=\xa00.86-1.0.'] Do intra and inter-tester reliability of the tuck jump assessment?
