Abstract. The purpose of this study is to examine the effects of the high school outputs on the students' achievement in the College of Sciences at Al-Hussein Bin Talal University. Since students' achievement is correlated with all major educational elements such as students, instructors, university administration, supervision, school administration, and other more, two elements are discussed in this study. These two elements are the high school students' achievements and the time of graduation. The sample of this study is applied on the 324 students of the College of Sciences at Al-Hussein Bin Talal students who attended the college on the academic years of 2004/2005, 2005/2006, 2006/2007, and 2007/2008; and those who graduated on the academic years 2007/2008, 2008/2009, 2009/2010, and 2010/2011. The first finding of the study is that students' College GPAs depend on their GPAs in high school and GPAs in their College freshman year? Another finding is also indicates that the students achievement in the College differs according to different high schools and different students' batches. Evidence is also found of the interaction between high schools and the time of graduation. Finally, the time factor is significantly associated with changes of students' attitude toward education and their vision toward future.
