Quiz

In order to achieve an official certification, one must:

• Attend certification training and pass the General, Specific and Practical examinations with a score of 80% or better.
• Documentation of education or experience must be maintained annually.
• Hearing acuity must meet the minimum requirement of one ear of less than 25 dBHL at 500 Hz to 4 kHz (with or without aid.) Hearing acuity examinations must be documented annually.
• Documented experience signed by a supervisor or superior for 6 months, additionally of the Level I experience of 6 months, for a cumulative 12 months’ experience to qualify for official certification of Level II.

Candidates for Level II certification should:
