Purpose: This article aims to investigate the challenges faced during the training and development (T&D) evaluation process from the point of view of faculty members and HR managers in Saudi Arabian public universities, and to examine the influence of these challenges on the effectiveness of T&D programmes in public universities. Design/methodology/approach: Exploratory research using semi-structured interviews to determine the challenges faced during T&D evaluation was employed. Participants included faculty members (n = 23) and senior managers (n = 05) working in four public universities in Saudi Arabia. The interviews were transcribed and subjected to thematic analysis. Findings: The outcome highlights the challenges faced during the T&D evaluation process: a lack of performance measurement and role ambiguity H.R.M. practices. Finally, this study aims to investigate how do these challenges influence the higher education sector. Originality/value: To the best of the researcher's knowledge, this is one of the first attempts to explore challenges within the T&D evaluation process in Saudi Arabian higher education. The results should therefore broaden the scope of the available literature and fill a research gap, particularly regarding the Gulf Cooperation Council (GCC) of Nations.
