The present research examined the influence of constructs representing social effectiveness on assessment center (AC) ratings in two samples. We expected different effects of self‐monitoring (SM) on different dimension ratings, a positive effect of the ability to identify criteria (ATIC) on the overall AC rating and a moderating effect of the ATIC on the relationship between SM and the dimension rating. Forty‐six (Study 1) and 115 (Study 2) applicants participated in ACs in field settings. Across both studies, SM had a negative effect on the integrity rating. No relationship was identified between SM and social sensitivity or problem solving ratings. In Study 1, the ATIC had a positive effect on the overall AC rating. No support was identified for a moderating effect of the ATIC on the relationship between SM and the social sensitivity rating.
