The study investigated into the identification of students’ perceived difficult concepts in senior secondary school chemistry in Oju Local Government Area of Benue State, Nigeria. Four research questions and three hypotheses were raised and formulated. 95 SSII chemistry students were used. The instrument for data collection was the chemistry students’ concept difficulty assessment questionnaire. The research questions were answered using percentages and mean scores while the hypotheses were analyzed using chi-square at 0.05 level of significance. It was found that there is no significance difference between male and female chemistry students in their perception of difficult concepts in SSII chemistry. It was recommended that both male and female chemistry students should be encouraged to learn chemistry with greater emphasis on female students.
