Important Notice: This buyers guidance and resources page is provided for historical reference only, as the OASIS program has officially ended.
To initiate a legacy OASIS Delegation of Procurement Authority (DPA) for modifying and administering an active OASIS task order, please follow the steps below:
Please note that CLPS and DPAs for legacy OASIS will no longer be issued. The OASIS program has concluded, and DPAs, which were previously required to award a task order, are no longer needed. Contracting officers can now self-certify to administer task orders, streamlining the process for task order management. For questions, contact us at oasisdpa@gsa.gov.
You can now place orders directly from OASIS+. For more details and to access the necessary tools to streamline your procurement processes, visit the OASIS+ website.

The OASIS program has created a variety of crosswalks to guide buyers through the acquisition process.
Review the North American Industry Classification System (NAICS) Code Definitions by OASIS Pool Numbers [PDF - 177 KB].
The core disciplines/scopes of the contracts include:
The remaining 840 SOC occupations can be added and priced at the task order level as ‘ancillary labor’
The OASIS Labor Category Crosswalk Table [XLSX - 80 KB] compares Industry’s functional job descriptions and specific the Office of Management and Budget (OMB) Standard Occupational Classification (SOC) system occupational descriptions. In this table, you will find more than a thousand industry job titles with suggested SOC occupation and OASIS LCAT matches.
The OASIS Table of PSC codes by OASIS pool number [XLSX - 67 KB] is excerpted from Federal Procurement Data System-Next Generation (FPDS-NG) and only includes those in scope. Select the link to search for your Pool number and the various possible PSC Codes that may apply. (Note: The white drop down arrows on the table will streamline the process.)
Note: Ordering Contracting Officers (OCOs) are required to identify, in each task order solicitation, the PSC that represents the principal nature of the work, and report these PSCs in FPDS-NG.
The core disciplines/scopes of the contracts include:
OASIS Unrestricted is a Full and Open contract whereas OASIS Small Business is a 100 percent Small Business Set-Aside contract (FAR 19.502) with the ability to do Socio-Economic Set-Asides (FAR 19.8 thru FAR 19.15) at the task order level. The OASIS 8(a) SubPools were developed to provide the 8(a) community expanded access to the OASIS Best-in-Class contract program while creating more options for federal agencies to meet their 8(a) business development program goals through both competitive 8(a) set-asides and 8(a) directed task order awards.
OASIS Unrestricted and OASIS Small Business are a family of 7 separate Governmentwide Multiple Award, Indefinite Delivery, Indefinite Quantity (MA-IDIQ) task order contracts that span 28 NAICS Codes and 6 NAICS Code Exceptions under the economic subsector 541 - Professional, Scientific, and Technical Services.
In accordance with FAR 52.216-22, Indefinite Quantity, paragraph (d), any task order issued during the active period of performance of the master contracts may proceed up to five years following the expiration of the contract ordering period. (Eg., a task order issued on the last day of the IDIQ’s active period of performance may be issued for a base and four option periods, and all option periods can be exercised per the Ordering Contracting Officer’s (OCO) determination).
The OASIS contracts have different start dates, due to onramps that followed the initial awards; therefore, we aren’t publishing the start date of the contracts. If you need to know a specific contract’s start date, please contact the OASIS Program Office at oasis@gsa.gov.
