After how many attempts must further preparation be completed before taking the board exam a fourth time?

The requirement for further preparation before retaking the board exam for the fourth time is designed to ensure that candidates are adequately prepared and have addressed any deficiencies that may have contributed to previous unsuccessful attempts. The choice indicating that further preparation is determined by the board reflects the variability in each candidate's situation. The board has the authority to assess whether the candidate has taken appropriate steps to improve their knowledge and skills before allowing another attempt at the examination.

This approach emphasizes the board’s role in maintaining the integrity of the profession by ensuring that only those who are suitably prepared can attempt the exam again. Each situation can vary greatly based on the individual's prior performance, preparedness, and the specific recommendations provided by the board. Hence, the requirement for additional preparation is left to the board's discretion, rather than being defined by a fixed number of attempts or preparations, ensuring a tailored approach to each candidate’s needs.
