What action is typically necessary if a Praxis test candidate decides to withdraw?

When a Praxis test candidate decides to withdraw, it is necessary to contact ETS and follow their guidelines. This is important because the Educational Testing Service (ETS) has specific procedures in place for withdrawal to ensure that the process is handled correctly. Candidates must communicate with ETS to officially record their intention to withdraw, which could involve completing certain forms or meeting specific deadlines. This action helps prevent any misunderstanding regarding the candidate’s test registration status and ensures that fees are appropriately managed, as there may be financial implications related to withdrawal.

The other options do not meet the necessary procedural requirements. Simply not showing up does not formally indicate a withdrawal and could potentially lead to penalties or marked no-shows on the candidate's record. Not taking proactive communication steps could result in confusion about the candidate’s status, making it critical to follow the established guidelines provided by ETS.
