Background: In higher education, the trainer required some essential competencies. The term competence is understood as skills, knowledge, and characteristics that enable tasks to be carried out effectively and objectives to be accomplished effectively in a given role in the context of the organization's strategic goals. The study's primary purpose is to understand the ongoing educational reforms aiming to facilitate student competencies demands clarification, development, and evaluation of what competencies are required for teachers, university instructors, and trainers. Methods: The present study was carried out as a systematic review and meta-analysis. This review adhered to guidelines set by the PRISMA statement for systematic reviews and meta-analysis. We systematically searched Google Scholar, ERIC (education), Scopus, ProQuest, EBSCO HOST, Sociological Abstracts (sociology), and Psych INFO (psychology) with the appropriate key terms databases to identify eligible articles on trainer competencies in HEI with the appropriate key terms. Heterogeneity in effect sizes was assessed for the single-level analyses using Cochrane's Q for significance testing and I2 to indicate the level of heterogeneity in interpretable form. Results: In an initial literature search, a total of 1282 articles were found on the trainer competencies in HEI.Fifty-three studies with measurable skills were finally included for meta-analyses. A total of 23 outcome measures were included in the current review. Many studies reported that the communication skills that developed Teacher competency were 14.63% (95% CI 8.92%-22.10%) followed by interdisciplinary/ collaboration work, which created teacher competency 16.86% (95% CI 10.08% - 24.96%). Conclusion: A teaching competency framework that can be used as a starting point for teacher assessment in higher education has been developed and validated. In contemporary society, the career of an academic trainer is special in both place and role. In addition, there is an association among learning materials, teachers, and students in the educational process, so it is essential to train teachers for the career, which should concentrate on equipping them with relevant skills and competencies.
