The main objective of this study is to explore students' self-assessment to increase students' learning outcomes in teacher training colleges in Meme and Fako Divisions. In-depth interviews and group discussions were used as instruments for data collection. Purposive sampling technique was employed in selecting the teacher training colleges used in the study and the participants. The sample size of the study constituted of 37 student-teachers for in-depth interviews and four group discussions made up of ten student-teachers each. The interviews and group discussions were analysed through content analysis, while focus group discussions were analysed following the procedure for analysing and reporting focus group results by Krueger (1998). The findings revealed that self-directed learning can be used to increase students' learning outcomes; self-designed project influences students' learning outcomes; self-reported assessment is linked with students' learning outcomes; and that knowledge of self is related with students' learning outcomes.
