Counselling practicum is essential to hone the skills and competencies needed. One competency to be had by the prospective counsellors is mind skills, which are metacognition skills to manage their thoughts to give adaptive responses and performance. This study aims to identify the effect of mind skills training on prospective counsellors' performance. This study used a correlation research design to measure 50 prospective counsellors' performance. The data result showed the variance of the mind skills and counselling performance scores. The Pearson analysis results showed significant correlations. Linear regression analysis showed that the mind skills had an effect and contributed to 12.5% of the prospective counsellors' performance. The results showed that the mind skills (rules, perceptions, self-talk, visual images, explanation and expectations) had their role and function in leading counsellors on their best performance. The implication of these results for prospective counsellors' education could include the mind skills training on the practicum course.
