Psychometric test scoring

In this talk, you will learn what to consider before starting to score psychometric tests, why hand scoring is less preferable due to error risk, and the key steps involved if you must hand score. Dr Tyler explains the importance of checking answer sheets for irregularities, using the correct scoring key, and accurately recording raw scores, all while stressing the value of double-checking your work to maintain reliability.

After this talk, you will:

• Understand the key considerations before starting a test scoring exercise.

• Know why hand scoring increases the risk of error and impacts reliability and validity.

• Be aware of reasons why hand scoring might still be necessary, such as cost or practical constraints.

• Recognise the importance of checking answer sheets for irregularities and unclear responses before scoring.

• Understand the need to use the correct and properly aligned scoring key for the test being used.

• Be able to check you are scoring the right part of the test with the correct answer sheet and key.

• Know that scoring usually involves counting the number of correct answers to obtain a raw score.

• Appreciate the importance of double-checking your scoring to avoid mistakes.

• Understand that the raw score, also called the observed score, is the initial outcome from scoring.

• Be ready to enter the raw score in the appropriate section on the answer sheet.

• Be prepared to use these principles on the specific tests provided to you in the course, even if the demonstration test is not identical.
