Past TAC Data

(Data for current -- TAC 2023 -- tasks is available only to registered TAC 2023 track participants. See the TAC 2023 page for registration information.)

The data available on this page include test data and evaluation results for past TAC cycles. (Task guidelines for past years can be found on the track home pages.)

A "Past TAC Data" ID and password sequence is required in order to access any data distributed by NIST on this page. Most data files can be downloaded directly from the TAC web site, but some files will require sending an email to tac-admin@nist.gov containing your "Past TAC Data" ID and password and the name of the requested file.

The "Past TAC Data" ID and password sequence is static from year to year and is different from any "Team" ID and password sequence that an organization may have received as a registered track participant in any TAC year (including the current year). To receive the required "Past TAC Data" ID and password sequence that allows access to past TAC data, please complete the "Agreement Concerning Dissemination of TAC Results" and any additional User Agreements that are required for the particular track, task, and year (See Table below). TAC Agreement forms are available at:

• TAC User Agreements Page

Send the Organization Applications to NIST, retain the Individual Applications at your organization. When you send your forms, please indicate that you are requesting 'Past TAC Data'. You will receive a response email confirming receipt of your forms. If this is the first time you are requesting "Past TAC Data", you will also receive a "Past TAC Data" ID and password sequence; otherwise, you may use your existing "Past TAC Data" ID and password to access the data.

* Agreement Concerning Dissemination of TAC Results is required for accessing any TAC data.
