The study of technical and applied courses at the Higher Institutes of Sciences and Technology requires mathematical skills and a prior mathematical readiness, and as a result of a complaint by a large number of faculty members in these institutes that students of higher institutes of science and technology do not have sufficient mathematical readiness to study their scientific specialties, which called on researchers to do this simple study to find out the extent of the allegations, as the researchers conducted an examination for a random sample of new students from the various departments of the Higher Institute for Sciences and Technology at Zawia, which measures the extent of these student's mastery of a number of mathematical skills, and then analyzed the results statistically, as the results showed that the degree of student's mastery of mathematical skills is weak and thus their mathematical readiness not sufficient for subsequent learning in the various departments, and based on these results, the researchers recommended adding an introductory mathematical course in which the concepts, relationships, methods and skills that the student needs to study the subsequent courses are presented and this course is a review of what has been studied in previous educational stages(primary-secondary) .
