What does not prolong the three-year period of provisional certification?

The correct answer identifies that disciplinary suspension does not prolong the three-year period of provisional certification. During the provisional period, a certified shorthand reporter is expected to improve their skills and ensure compliance with the standards set forth by the JBCC. If a provisional certificate is suspended due to disciplinary issues, it affects the individual's ability to work as a reporter but does not extend the duration of the original provisional certification period. In other words, the clock for the three years continues without any additional time being added because of a suspension.

In contrast, stagnant applications, additional training, and extended waiting periods are related to circumstances that could potentially affect a reporter's progression or status. Stagnant applications might refer to delays that could extend the process for qualifying for full certification, while additional training is generally intended to support a reporter's improvement and could lead to additional evaluations or requirements that might extend the provisional period. Extended waiting periods for exam results or certification processes could also delay the achievement of full certification. None of these scenarios directly relates to the period of provisional certification being unaffected, which is why disciplinary suspension stands out in this context.
