Abstract—Facility management competency questionnaire was developed to measure the facility management competencies required by individuals who manage the facility or facilities manager at the polytechnic. This study was conducted to produce empirical evidence of the reliability and validity of the competency of questionnaires facility manager by using Partial Least Square. This study used 36 items derived from the professional bodies and previous studies. This questionnaire administered 661 officers who manage the facilities in the polytechnics. The questionnaire measures five constructs, namely Leadership in Organization and Human Resources Management, Services Management, Operation and Maintenance Management, Working Environment and Resource Management and Law Management with six-point Likert scale. Partial least squares; SmartPLS version 2.0, was used to test the reliability and validity of the questionnaire. Reliability index values obtained from all constructs is between 0.909 and 0.969. This study also describes an arrangement of items in accordance with the importance being accorded agreed upon by those who manage the facilities in the polytechnics. Results acquired have proved questionnaires used have high reliability and validity for identifying facility manager competencies in polytechnic. Index Terms—Facility management competencies, reliability, validity, partial least square. I. INTRODUCTION The importance of facility management competencies is not a new thing in discussing, especially in developed countries like United Kingdom, United States and Australia. Everyone needs facility management competencies to function while doing the duty effectively [1]. Facility Management competencies also been discussed at various levels, including, professional bodies, and higher education institution. For example of activities undertaken by them such as courses, seminars, workshops, etc. (website [2]-[4]). While in Malaysia the Minister of Works had emphasized to all asset managers, facility managers and maintenance contractors to improve their competencies in carrying out their respective responsibilities at Asset and Facility Management Conference Malaysia (NAFAM) [5]. Competition for employment has made Human Skills even more important. Hence, a study to identify the most facility management competencies with the current situation of this industry in Malaysia is appropriate. To ensure that the process of identifying the precise competence and quality, the Manuscript received September 10, 2013; revised December 4, 2013. Mariah Awang is with the Department of Polytechnic Education, Ministry of Higher Education Malaysia or Universiti Teknologi Malaysia (e-mail: mariahawang@yahoo.com). questionnaire used for this study should have the reliability and validity due to the data, and the findings are recognized by all parties. A great many authors have discussed the requirements on the general competence of managers, e.g. [6]-[8], while others have concentrated on the demands placed on ICT managers [9]-[12]. Study the reliability and validity of of questionnaires is very important to maintain the accuracy of disability of questionnaires. The higher value for the reliability and validity of the questionnaire, the more accurate the data. Reliability is defined as a measure to determine the consistency of the scores of each item [13]. Consistency means that when the same items are tested multiple times on the same subject at different time intervals but still give a decision or answer score equal or nearly equal [14]. So, the validity is the appropriateness, truthfulness, meaningfulness and usefulness of questionnaires that enable data the inherent [15]. Consequently the objective of this article is divided into two: the first one; obtain the reliability of the facility management competencies of questionnaires. Second, find out the validity of facility management competencies of questionnaires. Therefore in order to achieve the objectives of this article, further discussion is the facility management competencies elements, methodologies, finding and discussion. II. FACILITY MANAGEMENT COMPETENCIES ELEMENT United Kingdom ten years ago has led to increased interest in the application of the competency framework in the development and selection of expert managers and general managers. Most of the works involved in developing this framework were focused upon the role of facilities managers [1].

These competency areas share some of the same competences: for example, in the field of human resources, communication competence and communication of information arise within the same field. Therefore, [17] have specified five areas of facility management competencies that are essential to realize the mission to the organization.
