Some questions to ask when considering reliability include:

• Will the assessment produce similar or comparable outcomes when a student takes the same test repeatedly over time (assuming that no new learning takes place in between tests)?

• Are there discrepancies in grades or test scores obtained when two or more markers grade the same student on the same assessment task?

• How will the reliability of the assessment change when the mode of assessment used changes, such as, from multiple choice questions to free-response format?

Some questions to ask when evaluating fairness include:

• Are the learning targets and assessment criteria made clear to all students?

• Are there sources of bias in the test questions which could distort the results for certain subgroups of the population taking the test?

• Is the test administered under standard conditions such that no student is unfairly advantaged or disadvantaged?
