My daughter is a Bioengineering major, currently in her senior year and looking at Master’s programs now. She has a specific interest but most of the programs she is looking at are only a year long. She has a short list of maybe 5 and I think one is a year and 1/2 but it includes an internship. I believe though at her current T20 school almost all the engineer disciplines offer a 4+1 program where the juniors or seniors can apply for a 5th year to complete their masters.
