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.

his study examined the psychometric properties of a Persian translation of the Fennema-Sherman Mathematics Attitudes Scales among a sample of 400 Iranian high school students. A structural equation modeling strategy via Lisrel 8 (with item parceling procedure) was employed in estimating parameters. In addition, confirmatory factor analysis was conducted to assess construct validity of the nine latent variables, with each latent variable measured by 12 observed variables. The results of this study indicate an acceptable fit between the proposed model and the observed data. From all the 108 items (measured variables), 91 items correlated with their respective factors at a reasonably strong level. In general, the Persian translation of the FSMAS has acceptable psychometric properties. The fit of the proposed confirmatory factor analytic model provides evidence for the scale’s construct validity. The sample used in the present study may be minimally representative of the general population and replication is needed. .
