B Tech distance education refers to a correspondence course at the undergraduate level with a time span of three to four years. Some important subjects taught in the B Tech correspondence course include Engineering Physics and Mathematics, Computer Programming, Engineering Mechanics, Engineering Graphics, Data Structures, Machine Design, and Analog Circuits. The primary goal of distance BTech courses is to offer flexibility to students who find it inconvenient to pursue regular BTech courses in India.

B Tech by distance learning enables students to complete education at their own pace and serves as a go-to option for working professionals who want to enhance their skills and knowledge alongside their jobs. The basic B Tech distance education eligibility criteria require students to complete Class 12 in the Science stream with a minimum of 50 percent marks in Physics, Chemistry, and Mathematics subjects. Admission to distance BTech courses is majorly based on the marks obtained in Class 12. Some of the popular distance BTech specializations include Electrical Engineering, Civil Engineering, Mechanical Engineering, Computer Science Engineering, and Electronics and Communication Engineering.

There are more than 100 colleges for B Tech correspondence courses in India, including the IIMTs in India, Karnataka State Open University, Wisdom School of Management for Distance Education, International Institute of Management and Engineering, and Aryabhatta Degree College. The average B Tech distance education fees is approximately INR 50,000 and INR 1.5 lakh.

Distance BTech graduates can work as Civil Engineer, Software Engineer, Mechanical Engineer, Electrical Engineer, Computer Science Engineer, Entrepreneur, etc. The average distance BTech salary is around INR 4 LPA to INR 6 LPA. However, there could be job restrictions faced by B Tech distance education graduates, as recruiters prefer regular BTech graduates over them. This is due to the regulations set by the University Grants Commission (UGC), according to which the distance courses for engineering and technology disciplines are invalid in India, owing to the practical and skill-based approach of these fields.
