The Director of the intake unit of a One-Stop Center requires that all customers with disabilities be automatically referred to a separate intake unit that provides only limited intake services. The Director would like to maintain the main unit’s productivity standard of processing a certain number of customers per day, and fears that processing customers with disabilities may slow the unit’s productivity. If a customer with a known disability refuses to go to the separate intake unit, he/she cannot register for the offered services. Is this practice a violation of Section 504 and its implementing regulations?
