Abstract: Collaborative learning has proven in promoting soft skills development and has been widely implemented in teaching and learning. However, this study addressed the lack of soft skills issue among Malaysia polytechnic graduates causing the graduate to face unemployment. It shows that collaboration does not happen naturally in a group. In previous studies, Online Project Based Collaborative Learning (OPBCL) was developed based on proposed model in order to enhanced student soft skills. A research testing instrument called Collaborative Learning Rubric (CLR) developed in order to evaluate the effectiveness of OPBCL. The main quality indicators for any of testing instrument in research are the validity and reliability. Therefore, this study aims to determine the validity and reliability of CLR. A number of 32 (N = 32) diploma hotel catering students from Politeknik Ibrahim Sultan, Johor (PIS) participated in this study. Data obtained was analysed using WINSTEP Version 3.68 Software. The finding showed that CLR had high reliability with two categories of difficulties items. So, it can be concluded that CLR is reliable and strongly accepted. All items will remain after Rasch analysis. It hoped that this study will give emphasis to other researchers about the importance of analysing items to ensure the quality of an instrument developed.
