Is ece polytechnic diploma is equivalent to graduation?

No, an ECE polytechnic diploma is not equivalent to a graduation degree (like a Bachelor of Engineering in ECE). A diploma is a shorter, more vocationally focused program, while a degree is a longer, more academically rigorous program. While a diploma can be a stepping stone towards a degree (sometimes allowing for advanced standing or credit transfer), it doesn't hold the same weight or recognition as a bachelor's degree in terms of educational attainment.
