This study examined physical education teacher education (PETE) majors' common content knowledge (CCK), performance, and specialized content knowledge (SCK) of volleyball to see whether there is a difference between non-PETE majors, and how much they improved, while they were in the PETE program. Twenty-two participants from a PETE major volleyball content course and 21 participants from a non-PETE major basic instruction volleyball course for the comparison group. Pre- and post-tests of CCK, performance, and two SCK variables were used for the majors, and one pretest SCK variable (task progression) was used for the comparison group. Data are reported both descriptively and inferentially. The PETE majors showed better scores on the pretest for the SCK variable (task progression). Also, the PETE majors had significantly improved scores from pre- to post-test for all four variables. It needs further research studies for the content course of the PETE program to find the best way to proceed.
