The heating, ventilation, and air conditioning (HVAC) industry needs a workforce with technical skills, knowledge of the newest technologies, and problem-solving abilities. Without a clear competency model, graduates' or employees' ability levels are difficult to align with industry standards, which affects the effectiveness of HVAC systems that are critical in various sectors and the quality of services they provide. As a result, this model is the primary guide when designing curricula, training, and assessments to ensure that the HVAC workforce can meet industry demands consistently and competitively. Thus, this research is developed to examine the empirical evidence on validity and reliability of the survey item of the mechanical executive competency by using Rasch Measurement Model Analysis to make the constructed item applicable to the formal large scale research setting. A total of 30 students with HVAC background from University Tun Hussein Onn Malaysia involved in this study. Beforehand, this research item has been validated by three competency and research experts from various faculties. WINSTEP software version 3.69.1.1 was used to analyse the data, and the results showed that the survey item had great reliability across four constructs. Based on the Person Reliability of 0.91 and Item Reliability of 0.88, it was concluded that the constructed instrument is reliable and can be used on a large scale. It is anticipated that by assuring the instrument's strong validity and reliability, researchers would be able to use or adapt this excellent instrument in their research. Several aspects of students' technical and interpersonal skills are at a moderate level and the finding obtained are significant to provide useful input for policymakers, educational institutions, and the sewerage industry, and help address the issue of unemployment and skill mismatch in Malaysia as a whole © Little Lion Scientific
