This paper aims to investigate how various writer`s and texts` variables correlate with academic critique`s quality of college students. Writer`s variables include prior topic knowledge and degree of source text comprehension. And text`s variables include length, organizational score, type of evaluative commentary, type of source of support and text configuration patterns. The analysis on the data showed the low correlation of topic knowledge and text`s quality(r=.437). But there was high correlation of the degree of source text comprehension and text`s quality(r=.899). As for the text`s variables, organizational score and type of source of supports were two major factors which had high correlation with text quality(r=.729, r=-.620). Against the result of prior studies, the portions of negative commentary had not high correlation with text quality score(r=.524), which means the type of writer`s approach to source text itself has low importance of text`s quality than the type and abundance of support.
