The purpose of this study is to examine and analyze the factors influencing students' choices of private universities in Saudi Arabia which include reputation, availability of academic programs, career opportunities, tuition fees, information sources and advertising, infrastructure and facilities, university location, student life programs, and family and friends' recommendations. The research uses primary data through a survey of 253 students at universities and high schools. Data were analyzed using multiple regression on Eviews software. The results of this study indicate that six factors have significant impact on the student's decision to choose a particular private university. The research revealed distinct decision making patterns among students based on age and gender. Younger students pay particular attention to university tuition fees, university facilities and the opinions of their family and friends. Undergraduates prioritize career prospects, tuition fees, and university reputation. In contrast, graduate students focus more on university infrastructure. Universities are advised to enhance their reputation by investing in infrastructure, improving the quality of teaching and research. This improvement can positively impact word of mouth reputation, which holds significant influence in the decision-making process, particularly when it comes to recommendations from family members and friends. This research contributes to the research on higher education in the Saudi context and provide practical implications for university administrators and policymakers.
