The purpose of the Thematic Programming Committee (TPC) is to create proposals for themes for upcoming ACS national meetings. Proposals need to be presented with enough lead time before a national meeting to allow a theme to be chosen by the Steering Committee, presented to the divisions for comment, and decided upon by the Steering Committee. The final decision on the theme needs to be made 24 months prior to the national meeting.
The activities of the TPC will include:
The following is a rough timeline that can serve to guide the work of the subcommittee:
| Due by (months prior to meeting) | Task | Responsible |
| about 32 (Generally 2 national meetings prior to one at which final decision will be made) | Send request to divisions, ComSci, others for ideas for theme for upcoming meeting | TPC/DDA Staff |
| about 29 | Collate suggested theme input from divisions, ComSci, others and send to TPC members | DDA Staff |
| about 28 (Generally at National Meeting prior to one at which final decision will be made) | Decide on theme to recommend to Steering Committee for upcoming meeting | TPC |
| 25 | Deadline for Division Feedback on Theme(s) | MPPG Steering Committee |
| 24 | Final Decision on Theme Made | MPPG Steering Committee |
