Although the official notice has not yet been published until March 2025, public tender experts already anticipate that competition will be fierce, with millions of applicants expected.
What is CNU and why does it stand out?
O Competition National Unified is an initiative coordinated by the Ministry of Management and Innovation in Public Services, with the objective of unifying the selection processes for the federal public service.
The proposal aims to democratize access to public vacancies and offer a more efficient selection, avoiding disparities between notices from different bodies.
Just as the National High School Exam (Enem) focuses on admission to higher education, the CNU focuses on admission to the federal civil service, with a standardized test model divided into thematic blocks.
In 2024, the first CNU was a milestone in the history of competitions in Brazil, with significant participation and a robust structure.
The 2025 edition promises to maintain this trajectory of innovation, with possible adjustments to further increase equity and transparency.

Writing can make a difference

Study in a group if possible
Exchanging knowledge, discussing doubts and sharing materials is a dynamic way of consolidating content.
Final considerations
CNU 2025 represents a great opportunity for those who wish to enter the public service with transparency and justice.
But, like every great opportunity, it requires preparation, strategy and focus.
Studying now, staying well informed and avoiding traps are attitudes that will make all the difference when the notice is finally published.
The competition will be tough, but with organization and dedication, it is possible to turn this opportunity into reality.
Stay tuned to official channels and invest in your future responsibly and consistently.
