Self-determination theory (SDT) guided comparison of competence satisfaction in a ball striking activity of elementary school students with (n =16) and without (n = 18) physical disabilities under mastery and performance climates. Consistent with SDT competence satisfaction was measured by risk taking (RT) and achievement (ACH). Performance climate increased RT, undermined ACH accomplishments for individuals with physical disabilities, and encouraged ACH for peers without disabilities. Nevertheless, no competence satisfaction difference between the groups was found in either achievement climate, suggesting competence was satisfied in different ways for the two participant groups. ACH (performance change) was important for all students, but RT was particularly important for those without disabilities. Performance climates should be used cautiously to challenge students with physical disabilities.
