This paper reports on a systematic literature review to understand better methodologies and data collection tools used to judge student teaching effectiveness, ways in which validity and reliability are considered, the processes involved in assessing new teaching effectiveness within teacher education programmes, and how evaluation and results are used to judge readiness to teach. The accurate and consistent judgement of teaching competence during and at completion of preparation continues to be an area of increasing interest and concern. The PRISMA review process identified 45 key papers. An in-depth analysis underscored several crucial factors, such as the challenge of ensuring the reliability of judgements within dynamic educational environments and the need for broader understanding and applications of reliability and dependability when making judgements. The findings of this systematic literature review hold implications that merit consideration by teacher education programmes for processes to judge teaching effectiveness. The analysis also highlighted the intricacies inherent in evaluating teaching effectiveness, alongside ongoing discourse regarding the criteria and measures for judging competence of student teachers.
