Final answer:
AIRS Standards do not mandate or prohibit fees for inclusion in resource databases but suggest that any fees charged should be reasonable and justifiable to avoid deterring essential service providers.
Step-by-step explanation:
The AIRS Standards (Alliance of Information and Referral Systems) address a range of practices to ensure quality in the operation of information and referral (I&R) services. When it comes to setting fees for inclusion in resource databases, the AIRS Standards do not recommend or mandate a fee, nor do they prohibit it. Instead, the AIRS Standards provide general guidance that any fees charged for inclusion should be reasonable, justifiable, and should not create a barrier to entry. Specifically, the AIRS Standards suggest that if fees are charged, they must be structured in such a way that they do not deter essential community service providers from participating in the I&R resource database.
