Level 1, student level (N = 779); Level 2, classroom level (N = 47); ASC_abs, absolute academic self-concept; ASC_ind, individual academic self-concept; ASC_crit, criterial academic self-concept; ASC_soc, social academic self-concept; Grades, averaged grades at the end of the school year 7 (Math, German, English as a foreign language, Biology); M_grades, aggregated mean-grades on L2; betaC, calculated context-effect (between-within); zbetaC, standardized context-effect by the SD of the predictor at L2 and the squared root sum of the criterion (Marsh et al., 2009); ∗p < 0.05, ∗∗p < 0.01, ∗∗∗p < 0.001.
