This paper presents evaluation of assessment systems for sustainability of higher education in KSA. Previously, student’s admission data to compare students’ performance in the High School Assessment System (HSAS) and in the National Assessment System (NAS) were used (Alnowibet and Ahmad 2015). This study is further extended to investigate the level of performance in both male and female students using both assessment system’s data in Saudi Arabia. A data set of university students specialized in selected specialties offered in Saudi universities is used. The outcome point out that there is a substantial student’s performance difference in both assessment systems. Also, the results clearly shows that there is substantial performance difference between both categories; female students perform significantly better than their male counterparts. This research study can assist the Education policy makers to ameliorate the effectiveness of the High School Assessment System in Saudi Arabia for the sustainable development of the education system. The findings of the research may be useful for education policy formulation in Saudi Arabia.
