In addition, ANCOVA requires the following additional assumptions: For each independent variable, the relationship between the dependent variable (y) and the covariate (x) is linear.

The standard linear regression assumptions hold; further we assume that the slope of the covariate is equal across all treatment groups (homogeneity of regression slopes).
