Valid and reliable jump shooting assessments that replicate in-game shooting performance are currently lacking in basketball. The aims of this thesis were to (1) describe the development of the newly-established Basketball Jump Shooting Accuracy Test (BJSAT), (2) determine the intra- and inter-rater reliability of the BJSAT, and (3) determine the content validity, construct validity, and test-retest reliability of the BJSAT. Basketball athletes from different playing levels (State Basketball League [SBL], n = 30, age: 22.7 ± 6.1 yr; SBL Division I, n = 11, age: 20.6 ± 2.1 yr) completed four trials of the BJSAT with each trial consisting of four two- and four three-point shots from predetermined court locations. Each shot attempt was scored utilising criteria where greater scores were given when superior accuracy was exhibited. The BJSAT detected a significant, large difference in accuracy between two- and three-point shots (d = 0.99, p < 0.01), representing suitable content validity. However, a non-significant, trivial difference was revealed in BJSAT score between gender (d = 0.17, p = 0.57) and playing level (d = 0.15, p = 0.70). For intra-rater reliability, there was an almost perfect (k = 0.85, p < 0.01) agreement between scores. The agreement for inter-rater reliability was rated as substantial (k = 0.70, p < 0.01). Relative reliability was rated as moderate for all athletes (intraclass correlation coefficient [ICC] = 0.71, p < 0.01) and good for the SBL athletes (ICC = 0.78, p < 0.01) highlighting sufficient reliability of the BJSAT when using the average of repeated scores. Absolute reliability for all athletes was above the acceptable benchmark (coefficient of variation = 16.2%); however this outcome is superior to comparative skill tests available in the literature. Floor and ceiling effects were absent in the BJSAT when one or multiple assessors scored the test. In conclusion, the BJSAT is a skill assessment where one or multiple assessors can reliably score jump shooting performance and is sensitive to two- and three-point shooting accuracy from variable distances and locations, representative of basketball game-play.
