Having a JBT diploma is the minimum educational qualification required for becoming a primary school teacher (Classes 1 to 5) in government schools.

You need to qualify for the Teacher Eligibility Test (TET) conducted by the National Testing Agency (NTA) or the State TET authority.

• CTET: The Central Teacher Eligibility Test (CTET) is a national-level exam for aspiring teachers.
  
  
• State TET: Many states conduct their own TET exams as well.
  
  Focus on preparing for the TET exam. The syllabus typically covers Child Development and Pedagogy, Language 1 (Hindi/English), Language 2 (Any other language), Mathematics, Environmental Studies, and Social Sciences. There are various resources available online and offline to help you prepare for the TET exam.
  
  Keep an eye out for government job notifications for primary teacher positions. These are typically advertised by the School Education Department of the state you are interested in working in.
  
  Once you see a job notification that matches your qualifications, apply online or through the designated mode mentioned in the notification.
  
  
  The selection process for government teaching jobs usually involves a written exam, followed by a skill test or interview, and document verification.
  
  While a JBT is sufficient for eligibility, pursuing a Bachelor of Education (B.Ed) degree can enhance your career prospects and make you eligible for teaching positions in upper primary classes (Classes 6 to 8) as well. Although not mandatory, prior teaching experience in private schools can be beneficial when applying for government teaching jobs.
