assumptions for Repeated Measures ANOVA

For the repeated measures ANOVA, do we only have the assumption of sphericity? Or do we also have the assumptions of normality and homogeneity of variance? I noticed in an earlier post that we test normality in the same way, but do we need to do this?

    For repeated measures ANOVA, you will need to check the assumption for normality and sphericity.

    Also, know that if you meet the assumption for sphericity, you also meet the assumption for homogeneity.

    ...in a fully related (or fully repeated) design. In a Mixed Design, you will need to test for Homogeneity of Variance.
