Final answer:
A practice permit must indeed be presented for inspection when requested by employers or the public, to verify the holder's authority to practice.
Step-by-step explanation:
It is true that a practice permit must be on display or made available for inspection upon the request of employers or the public. This is a common requirement across many professions where a permit or license is required to legally practice a trade or profession. The purpose of this requirement is to ensure that the individual is currently authorized to practice and meets the standards set by the relevant licensing body. It also provides transparency and accountability, allowing for the verification of qualifications by those who may be affected by the services provided.
