Centa stands for centre for teacher accreditation

"Centre for Teacher Accreditation (CENTA ^® ) is making teaching an aspirational profession by assessing and certifying the competencies of teachers, connecting them to career opportunities, rewards and recognition , and supporting their professional development . CENTA ^® equally helps schools and systems attract, develop, grow and retain great teachers. This leads to a virtuous cycle where many more teachers are motivated to improve their competencies and aspiring teachers see this as a valid career option – therefore fundamentally improving the quality of education ."

The registrations for teacher professional Olympiads are going on. You can refer this link
