The relation between B.Tech and Diploma courses is that B.Tech can be a degree course while Polytechnic can be a diploma in engineering. B.Tech, the duration of the course is 4 years, but the next entry is usually delivered in the second year if one has done a polytechnic course.
One can choose a polytechnic course just after 10th or do it after 12th. B.Tech is a degree course while Polytechnic is a diploma in engineering degree. it would be great if you did a B. tech after diploma because it will elevate your career vision. There are many colleges and universities that offer lateral entry into the B. Tech 2nd year and that could save your one year as well.
An engineer is someone who can plan, design, and perform work. The diploma holder is in the management category of the person working under the engineer to get the engineering plans done on the field. Previously Diploma was the last course. These days they will continue with higher education and progress in their work.
Polytechnic will help you to do technical work and get a job such as technical assistant, mechanic, service engineer, repair mechanic, technician, etc. while engineering degrees can help you to become a top private position or government enterprise. You can become a project engineer too.
The basic difference is the two-year period one spends in grades 11 and 12 and that makes the difference between these two activities. If a person has no interest in academics and does not want to pursue higher education then the best course is, in that case, to go to a polytechnic course that can be very helpful in getting a professional job even though you are at a lower level than engineering degrees. Polytechnic is a diploma and B Tech is a graduate course.
