Starting January 1, 2026, ACM will fully transition to Open Access. All ACM publications, including those from ACM-sponsored conferences, will be 100% Open Access. Authors will have two primary options for publishing Open Access articles with ACM: the ACM Open institutional model or by paying Article Processing Charges (APCs). With over 1,800 institutions already part of ACM Open, the majority of ACM-sponsored conference papers will not require APCs from authors or conferences (currently, around 70-75%).

Authors from institutions not participating in ACM Open will need to pay an APC to publish their papers, unless they qualify for a financial or discretionary waiver. To find out whether an APC applies to your article, please consult the list of participating institutions in ACM Open and review the APC Waivers and Discounts Policy. Keep in mind that waivers are rare and are granted based on specific criteria set by ACM.

Understanding that this change could present financial challenges, ACM has approved a temporary subsidy for 2026 to ease the transition and allow more time for institutions to join ACM Open. The subsidy will offer:

• $250 APC for ACM/SIG members
• $350 for non-members

This represents a 65% discount, funded directly by ACM. Authors are encouraged to help advocate for their institutions to join ACM Open during this transition period. This temporary subsidized pricing will apply to all conferences scheduled for 2026. Thank you.

The SIGAPP Student Travel Award Program (STAP) was established to provide financial support for SIGAPP student members to attend SIGAPP primary conference (SAC) to present their accepted work. Student primary authors and co-authors are eligible to apply for these awards. The eligibility rules may vary year to year depending on funds availability. Applications are evaluated on a competitive basis. Expenses eligible for coverage include conference registration fees, travel expenses to and from the conference, and accommodation expenses while attending SAC. Note that meal expenses will not be covered by these grants, neither will cost related to getting a visa to travel to the conference location. The award amounts vary year to year depending on type of travel (intercontinental or intra-continental) and the applicants pool and their needs. SIGAPP expects institutions to share costs in funding students travel to SAC. Reimbursement is handled by ACM after the end of the conference. Recipients will received instructions from ACM on how to claim these awards. Recipients need to keep original receipts for all eligible expenses as they are required for reimbursement. Students may join SIGAPP for a very nominal fee and become eligible for this funding. Only SIGAPP student members are eligible for this award. Please see SIGAPP Student Membership for more details.
