The purpose was to develop a valid and reliable battery of quad rugby skill tests. Participants were 65 adult, male, quad rugby athletes. Content validity was established in two modified Delphi rounds by a panel of international experts. For concurrent validity, Spearman rho correlations between coaches’ rankings of players’ skills and scores ranged from .63 to .98 for the total battery. For construct validity, principal factor analysis with oblique rotation revealed two factors. Intraclass reliability coefficients ranged from .94 to .99. The battery includes five tests: maneuverability with the ball, pass for accuracy, picking, sprinting, and pass for distance.

The purpose of the study was to examine the offensive game efficiency of elite wheelchair rugby players with regard to their International Wheelchair Rugby Federation (IWRF) classification. Male athletes (105) representing 12 European nations competing at the 2005 European Wheelchair Rugby Championships took part in this study. The primary recording instrument was the Game Efficiency Sheet (GES), an instrument designed to objectively record parameters of wheelchair rugby efficiency such as points scored, steals, turnovers, balls caught (%), and balls passed (%). Kruskal-Wallis between groups analyses identified significant differences among the lower classification groups (0.5–2.0) and between the lower and higher classification (2.5–3.5) groups. Further research is needed in identifying game efficiency differences in higher class groups.
