Evaluating an assessment battery for a multi-disability commercial college

[摘要] The present research study evaluated an unresearched assessment battery used to determinestudent trainability at a multi-disability commercial college.The issues of validity - specifically criterion-related validity and content-related validity anddynamic assessment were the main focus of the study. Revisions to the assessment batterywhere necessary were recommended,Fifty-two students from the multi-disability college formed the sample population forestablishing the criterion-related validity of the assessment battery. Students assessment resultswere correlated with the number of credits .hey obtained on course completion using the PearsonProduct Moment Correlation Coefficient. This research established that useful inferences aboutstudent trainability could be made from the existing assessment battery scores.Establishing the content-related validity of the assessment battery was a two foid process.Firstly, course lecturers completed a self-administered questionnaire to determine what skills/attributes were necessary for success in the four courses offered at the College. Secondly, aworkshop was held with a multi-disciplinary team of professionals to determine what skills/attributes were being tapped by the various sub-tests of the battery. It was established thattwelve of the skills/attributes necessary for course success were not tapped on the existingassessment battery. Measures which tap these skills/attdbutes need to be included in theassessment battery so that its content validity can be established.Given the controversy relating to standardised/static testing it was important to research therelevance and usefulness of the introduction of a dynamic assessment component to the existingbattery. Dynamic assessment would allow for learning potential to be tapped. Analyses ofvariance were conducted to determine the relationships between the variables - race, educationallevel and type of disability with performance on the assessment battery. The significantrelationships between educational level and performance and type of disability and performance
