The most common practice in scale development consists of an administering a group of items intended to measure the same construct and subsequently aggregating the responses to form total a scale value. Besides, reliability of scores, number of underlying constructs, and scale construction practices should empirically test the assumptions of equal item weighting and the linear treatment of scales can represent the quantity of a trait held by an individual. Based on the perspective of using Rasch Model as a model in one sense in that it represents the structure which data should exhibit in order to obtain measurements from the data; i.e. it provides a criterion for successful measurement.
