* A Bachelor's Degree: Almost universally, a bachelor's degree is the minimum requirement. This degree should ideally be in Computer Science, Information Technology, Software Engineering, or a closely related field. A strong foundation in programming, data structures, algorithms, and computer architecture is crucial.
* Postgraduate Qualification (Often Preferred or Required): Many regions prefer or even mandate a postgraduate degree (Master's degree) in a relevant computer science field. This demonstrates a deeper understanding of the subject matter and advanced pedagogical skills.
* Teaching Qualification/Certification: In addition to the subject matter expertise, most jurisdictions require a teaching certification or license specifically authorizing the teacher to instruct at the secondary school level. This often involves completing a teacher education program or passing relevant examinations.
* Experience: While not always a formal requirement for initial hiring, practical experience in the computer science industry or research can be highly advantageous. It allows teachers to provide relevant real-world examples and connect classroom learning to professional applications.
In summary: While a bachelor's degree in a relevant computer science field is a minimum, a master's degree and a teaching certification/license are often preferred or required to teach computer science at the higher secondary school level. The specific requirements should be checked with the relevant education ministry or department in the specific region.
