An Empirical Analysis on Mathematical Academic Achievement Test Based on IRT

SHEN Nan-shan(Dept of Math,West Anhui University,Lu'an Anhui 237012,China)  
Mathematics academic achievement of proficiency test is based on the national mathematics curriculum standards,which is criterion-referenced evaluation that constructed professionally in order to assess student mathematics learning quality in basic education.Through stratified sampling,774 valid subjects distributed in the different types of schools are to be for mathematics academic achievement testing.We analysis Analyse the test dates in applying the IRT parameter model and obtain four judgments:(1) Test scores and the best scores should be positively distributedshow negative skewness;(2) the test information function should be offset to the negative direction,so that there would be generally show a double waveform.(3)The subject item is poorly fit with the logistic models;(4) There is an obvious difference among the mathematics academic achievement levels of different types of schools.
