Abstract
Students have experienced errors in solving linear programming so that it could affect their performace and learning in this subject. The present study analyzed the errors using an in-depth eror analysis on linear programing students- problem solving efforts at different points in this subject to predicting student difficulty on some test items wich are most persistent. Results indicate that various types of errors occur in different points and this is an indication of linear programming achievemet difficulties. Many of the errors made by students are due to concept and procedural errors in solving linear programming. Recommendations for the necessity of certain errors are discussed.
