I learned in the RSA in Israel for almost 20 years and can testify that the Yeshiva nor staff encourage the students to go to college.
It is the parents that push their children to get a degree and the Yeshiva only allows in special cases to take a couple of evenings off of Torah learning, otherwise the parents will insist on them going to college full time.
The Yeshiva is an exellent place for students to develop their skills in learning and character development (Midos)
