TEA has posted guidance regarding purchases made with federal funds during an emergency such as Hurricane Harvey. In the event of an emergency, a grant recipient may choose to solicit a non-competitive proposal from only one source to avoid delay in procuring items or services (2 CFR 200.320(f)(2)).
Understandably, districts impacted by Hurricane Harvey may need to use the non-competitive proposal method of procurement to quickly purchase needed items or services. This method of purchasing does not relieve the district's responsibility to ensure that all costs are allowable under the program.
Districts and charter schools should keep information locally regarding how the determination was made. If the school prefers to obtain prior approval from TEA as their documentation for auditors, TEA has developed the appropriate approval mechanism.
