On-the-job graduate students are a form of education for on-the-job personnel, and their enrollment requirements usually vary with different schools and majors. Generally speaking, in-service postgraduate enrollment requires candidates to have a bachelor's degree recognized by the state, but the secondary school education does not meet this requirement.
Some schools or majors may have flexible academic requirements for candidates, allowing candidates with professional skills and practical experience to apply. However, it should be noted that these situations are few, and the specific requirements and enrollment policies will change with different schools and majors.
If you are interested in applying for on-the-job graduate students, I suggest you first understand the enrollment requirements and policies of various schools and majors, especially the specific regulations for candidates with secondary school education. You can get this information by consulting the enrollment brochures of relevant schools, official website or consulting relevant institutions.
If you have a technical secondary school education, but you don't meet the academic requirements of on-the-job graduate students, you can consider improving your academic level by self-study or attending adult education. With a nationally recognized undergraduate degree, you can choose more opportunities to apply for on-the-job graduate students or other forms of higher education.
What I want to emphasize is that although secondary school education may make you face some restrictions when applying for on-the-job graduate students, as long as you have professional skills and practical experience, you can still succeed in your career development through continuous learning and improving your ability. Whether you can apply for in-service graduate students or not, you should keep your enthusiasm and efforts in learning and constantly improve your comprehensive quality and ability.
I hope my suggestion will help you! Please feel free to tell me if you have any other questions or need help!
