الملخص EN

This study aimed to provide a self-confidence scale for the students of Algerian university, it is self-confidence scale designed by Anzi (2001) which was prepared on the Kuwaiti environment where the study focused on trying to identify the psychometric properties of the scale after its application to a standardization sample and its consistency with good test characteristics, and then building performance standards that explain raw scores.

In order to achieve this goal a sample of 438 individuals were selected in stratified random sampling from various social sciences departments in universities of: El Oued, Biskra, Ouargla.

To verify the hypotheses of the study, a copy of the original test was obtained.

For the test application, several copies were provided.

After application and data collection, data was analyzed and the performance standards for the study sample were got.

In addition, averages and standard deviation for all of sample individuals were extracted.

Also, item discrimination and quantitative indicators of the psychometric characteristics (test reliability and validity), were identified.

First, reliability coefficients were found in two ways: split-half method (Guttman formula) and Cronbach's alpha coefficient (α).

The study also found the performance standards represented in measurement method to deviation scales (5 categories)
