Acquisition Streamlining & Standardization Information System (ASSIST)

Last Updated : 04/29/2024
This is a Common Access Card (CAC) or External Certificate Authority (ECA) enabled Tool.


ASSIST is the official repository for defense and federal specifications and standards prepared under the Defense Standardization Program (DSP). ASSIST is a robust, comprehensive web site used by standardization management activities to develop, coordinate, distribute, and manage DSP technical documents. Managed by the DSP Automation Office (DSPAO) in Philadelphia, ASSIST also provides access to selected international standardization agreements, such as NATO standards ratified by the United States and International Test Operating Procedures; however, these types of documents are not available from Quick Search. Since it always has the most current information, ASSIST is the official source for specifications and standards used by DoD. There are technical documents indexed in ASSIST, and the ASSIST document database has PDF files associated with of the indexed documents. Most of these DSP documents may be accessed from one of three different types of ASSIST websites:

  • Public site: ASSIST Quick Search (http://assist.dla.mil) - provides access to all DSP documents that have been cleared for public release. 
  • Public-restricted site: ASSIST (https://assist.dla.mil) - like Quick Search, provides access all DSP documents that have been cleared for public release; however, in addition to the [Basic Search] and [Text Search], users may use a more robust [Advanced Search] that includes additional filters, or use a legacy [Direct Search] that may be useful when searching for a specific slash sheet. Users must complete an online registration form to request a user account and password. 
  • Private site: ASSIST (https://assistca.dla.mil) - can only be accessed by users on a DoD network using a common access card (CAC). After obtaining an ASSIST user account and password and using them to log onto the public-restricted to associate those credentials with their CAC, thereafter users may log onto ASSIST with their CAC and will be directed to the private site. Besides having all of the features of the public-restricted ASSIST, DOD users on the private may be able to access some controlled distribution documents and have access to the Weapon System Information Tool, which provides insight about how often specifications and standards are used to support acquisition. 

Note that there are several separate tools identified on the DAU tools website containing an ASSIST acronym. To avoid confusion, they include:

This government tool is included in the product support analytical tools database to assist defense acquisition workforce members with identifying product support solutions which potentially optimize system readiness and life cycle cost. The analytical tools database itself should under no circumstances be considered all-encompassing; nor does it in any way warrant or endorse the capabilities, pricing, and/or products of any particular individual, company, capability, or organization. Suggested updates to the description of this particular tool or additions to the tools database are welcome.
