The NIST Threshold Call (NIST IR 8214C) specified a “Previews” phase where teams have three opportunities to present their plans of upcoming package submission. Each preview phase requires submitting a Preview Writeup and then giving a corresponding Preview Talk.

Upcoming session: TCPT #2 (July 07–08): Threshold Call Preview Talks Round 2 (ZoomGov link)

• Previews Talks Phase 1: Presented at MPTS 2026 (Jan 26–29)
Previews Talks Phase 2: Presented at TCPT2 (July 07–08). (See schedule below)
Previews Talks Phase 3: Upcoming (Writeups by July 31; Talks TBA)

Participation in any session of Preview Talks requires abiding by the Code of Conduct for NIST conferences.

Preview writeups are posted in the MPTC website, within the submissions webpage:
Previews Writeups Phase 1: 26 preview writeups
Previews Writeups Phase 2: 10 preview writeups
Previews Writeups Phase 3: TBA

The 2nd phase of previews will be held on July 07–08, 2026, including virtual presentations of 10 preview talks. The corresponding Preview Writeups will be posted in the MPTC-Submissions webpage.
