construction, reliability making and validation of measurement tool for accreditation and quality assurance of iran's higher education

this study been done to build, reliability making and validation an measurement tool for accreditation and quality assurance of iran's higher education system. to perform this study, is used mixed method with explorative plan- tool development model.First, in the qualitative study, by using the method of grounded theory and interview with 36 higher education experts, were designed questionnaire with 25 omponents and 157 sub-components. then, in the quantitative section, Designed questionnaire, in a pilot study, was conducted on 84 members of Iran's higher education experts. based on the received feedback were acting to refine the questionnaire. then, the its final version and modified was put in the hands of 293 the country's higher education experts. validity of the questionnaire was confirmed by experts and its reliability was calculated equal to (0/982) by Cronbach's alpha. in the qualitative part of the study, was used non-probability purposive sampling sampling method and in the quantitative part, random classified sampling method used. to test mentioned measurment tool, analysis of structural equation modeling was used. by doing first order confirmatory factor analysis, mentioned measurment tool were modified to 22 components and 150 sub-components. results of second order confirmatory factor analysis, also showed that 22 components were extracted has sufficient factor load to predict of measurment tool relating to Accreditation and quality assurance of iran's higher education system. in addition, goodness of fit indices such as, (CMIN/DF) equal to 1/924, (RMSEA) equal to 0/39, (GFI) equal to 0/976, (AGFI) equal to 0/939, (CFI) equal to 0/928, (NNFI) equal to 0/935, (TLI) equal to 1/000, (IFI) equal to 0/928 and (RFI) equal to 0925, it shows, designed, measurment tools for the accreditation and quality assurance of iran's higher education system is a very favorable fitness.
