Understand the exam
Exam overview
There is no single State TET website, and that is the first thing to understand. Every state conducts its own Teacher Eligibility Test through its own examination authority or school education board — UPTET in Uttar Pradesh, MAHATET in Maharashtra, and an equivalent in each other state. Each has its own notification calendar, syllabus, application portal, fee and reservation rules. A link to one state's portal would be wrong for everyone in the other twenty-seven.
How to find yours. Go to the school education department or examination board website for the state you intend to teach in, and look for the TET notification. Search for the state name together with "TET official notification" rather than trusting the first coaching site that appears — those sites frequently carry outdated dates and unofficial application links. Confirm the notification PDF is hosted on a government domain before you pay any fee.
State TET or CTET? CTET, conducted by CBSE, is the central equivalent and is required for central government schools such as Kendriya Vidyalaya and Navodaya Vidyalaya. A state TET is required for that state's government schools. Many candidates take both, because they qualify for different sets of vacancies. Some states also accept CTET alongside their own test — check your state's rule rather than assuming.
What the certificate actually gives you, and this is the part people get wrong. Qualifying a TET is an eligibility certificate, not a job and not a guarantee of one. It allows you to apply when a teacher recruitment notification is issued. Those notifications are irregular, and in several states years have passed between them. Lakhs of people across the country hold a valid TET and no post. Plan for the qualification and the wait as two separate problems, and keep earning while you wait.
The validity period of TET certificates has been extended in recent years — confirm the current position for your state, since this has changed and may change again.
