The purpose of this study is to evaluate the content validity for creative thinking skills assessment that support conation aspect of prospective biology teacher. These procedures can be use in a variety of situations were judgements of the content validity of item or questionnaires are made on ordinal rating scales. A panel of six subject-matter experts (SMEs) rated the representation of content based on relevance, construction, and clarity. Computing data set using the Aiken’s V formula for determining the statistical significanceof V for small samples of raters on the five point scale are given. The result, of 52 items, those with content validity coefficient greater than 0,79 (48 items) remained and the rest (four items) were discarded.
