India has developed its own student assessment survey systems called the National Assessment Surveys (NAS), which are independently conducted by National Council of Educational Research and Training (NCERT) across the country on the latest international Item Response Theory (IRT) methodology. The NAS is conducted for classes III, V, VIII & X i.e. the critical stages of education early primary, end of primary, upper primary and secondary levels. The NAS is conducted every three years and provides detailed information on learning outcomes, which is useful for teacher training, curriculum development and for improving quality of education. The Central Board of Secondary Education (CBSE) has also introduced a test called Problem Solving Assessment (PSA) for the student in classes IX and XI from the year 2013, which gives students an exposure to application - oriented testing.
