“Validity refers to the extent to which a study actually captures or measures what it purports to examine. Two broad categories of validity are external and internal validity. External validity refers to the generalisability of the research findings. For example, would our findings from a particular study also apply to other groups, other geographical areas, etc.? Internal validity essentially refers to how confident the researcher is in the study results. This type of validity encompasses a range of issues from how rigorous the study was in terms of research design, sample, measures, etc. to whether the measures are measuring what they are supposed to measure. In this description of validity we will focus on this second area, the extent to which measures capture what they are purported to capture.� So, is the QEPT measuring what it is meant to be measuring? From a design viewpoint 5 dimensions/items were chosen from the Nepal Quality Education Framework which were then converted into a number of indicator statements. For example, #5 Pedagogy & Assessment, contains four statements classically describing the required inputs for Child Centred Development. Therefore we can assert that internally, the questions themselves relate directly to the requirements of quality education both generally and as specified by the Nepal Quality Education Framework. In addition we conducted separate assessments of changes in pedagogy style and measured changes and movements from a teacher centred style to a child centred style. Some results comparing child centredness with QEI score is shown below:

Once again there appears to be some correlation between changes in pedagogy style and increasing Quality Education Index showing that the QEPT is measuring the effect of pedagogy on quality as measured by children’s perceptions. Finally we have begun to monitor exam results and completion rates but this is obviously a longer study and will take some time to gather the data. For the moment however we believe that we can state that the QEPT has an acceptable level of validity.
