Sisu: Ministry of Education institutes extra phase of unified selection to fill remaining university vacancies

Governo Federal established a new stage of entry into public higher education for the year 2026. Ministério of Educação structured Sisu+, a complementary modality of Sistema of Seleção Unificada aimed exclusively at filling seats that remain empty in federal and state institutions. The measure aims to optimize the filling of classes after traditional waiting lists are exhausted. The mechanism works as a technical recap within the government platform.

The initiative does not constitute an unprecedented or independent selection process. The tool operates as an operational annex to the regular edition of the program, taking advantage of the data infrastructure already existing in the higher education access portal. The focus is on the portion of candidates who showed initial interest in entering university, but who finished the main phase of the academic calendar without any formalized institutional link.

Critérios of eligibility and blocks in the federal system

Participation in Sisu+ requires compliance with strict eligibility rules set by Ministério of Educação. The system only accepts students who registered in the regular stage of Sisu 2026. The candidate must have gone through the entire initial process of choosing courses without obtaining approval, or have been selected in a call and chosen not to sign the enrollment documentation at the educational institution. Participation history for the current year becomes the primary requirement for access to the complementary platform.

The notice establishes automatic blocking for specific student profiles. Pessoas who performed the Exame Nacional of Ensino Médio, but ignored the regular Sisu registration period, lose the right to compete for the remaining places. Exclusion occurs systemically. The block also affects any candidate who already has an active enrollment in a public university achieved through the main edition of the program in 2026. The guideline prevents students already allocated to higher education from using the extra phase to change courses or institutions, reserving opportunities strictly for those outside the university system.

Aproveitamento grading and grading dynamics

The Sisu+ note processing architecture presents operational differences compared to the traditional model. The complementary system expands the window for taking advantage of candidates’ performance. The government platform allows the use of results obtained in the three most recent editions of the national exam. The mechanism crosses the participant’s data with the Instituto Nacional base of Estudos and Pesquisas Educacionais Anísio Teixeira.

Candidates can enter the race using the scores recorded in the following years:

• Enem 2023
• Enem 2024
• Enem 2025

Educação’s Ministério software performs an automatic calculation to determine the student’s position in the competition. The system evaluates the performance report for each valid year and selects the edition that provides the highest weighted average. The mathematical operation considers the specific weights assigned by each university to the areas of knowledge required in the different courses. Algorithmic flexibility ensures that the candidate competes with their best possible historical score, balancing the chances between participants with different evaluation trajectories.

Prazos institutional and university obligations

Higher education institutions have their own administrative calendar for adhering to the complementary format. Reitorias and undergraduate departments have until May 29, 2026 to formalize their interest in offering their vacant chairs at Sisu+. The participation term requires compliance with minimum availability quotas. Cada university must provide at least two places per course and per operating shift. Federal regulation requires that, within this minimum offer, there is a guarantee of at least one vacancy allocated to the broad competition modality, regardless of the volume of seats reserved for affirmative action policies.

The registration schedule for students remains linked to the work pace of universities. Ministério of Educação conditions the opening of the Sisu+ portal to the definitive closure of all calls on the regular waiting list. The exact start date of the complementary phase depends on the completion of the internal selection processes of the participating colleges. The federal government will publish the official access calendar for candidates only after consolidating the national table of remaining vacancies reported by institutions by the end of May.

Flexibilidade in choices and updating socioeconomic data

The Sisu+ enrollment environment offers autonomy in reconfiguring academic choices. The candidate has the right to select up to two undergraduate course options. The appointments made in this complementary stage are completely independent of the history of preferences registered in the regular phase of the program. A student who tried to enroll in Engenharia at the beginning of the year can use the new opportunity to compete for a place in Administração, depending exclusively on availability in the remaining course catalog.

The platform allows the complete review of the user’s competition profile. After Durante fills out the form, the participant can update the socioeconomic questionnaire and change the dispute modality. A candidate who competed in the broad competition in the main stage can migrate to the quota system, if their situation meets the income or public school criteria. Validation of the declared information occurs at the time of in-person or digital registration. Universities maintain rigor in requiring supporting documentation for those enrolled in affirmative action policies, following the same audit protocols applied in the conventional selection process.

Impacto in occupation of the public higher education network

The implementation of Sisu+ tackles a chronic problem in the administration of Brazilian public universities. Anualmente, institutions register a significant volume of vacancies that are not filled even after successive calls from the waiting list. The phenomenon of idleness affects courses with lower historical demand with greater intensity, degrees offered in alternative shifts or campuses located outside large urban centers. Early dropout and withdrawal of successful candidates generate high operational costs for the federal and state education network.

The new format acts as a scanning tool in the education system. The modality reuses the residual demand from students who maintain an interest in academic training, connecting this audience directly with the idle installed capacity of colleges. The requirement for a specific notice for Sisu+ organized the flow of information between the federal government and the rectors. The program consolidates an extra stage of allocation of public resources without changing the base legislation of Sistema and Seleção Unificada, functioning as an efficiency adjustment in the management of university enrollments.
