For example, the Wall Street Journal reported that Stanford University had a record low admission rate this year. The newspaper said the California school accepted less than eleven percent of the students who applied.
College admissions officers give a number of reasons for the higher rates of rejection letters this year. They say the main reason is that high school seniors are applying to more schools than in the past Some colleges reported big increases in the number of applications. Another reason is the general increase in students going to college.
Electronic forms make applying easier. For example, students can send an online form. called the Common Application to many different colleges and universities.
Many students who apply to top schools are placed on a waiting list. They do not get a decision until the school knows how many applicants who are offered admission will accept the offer. Just as students compete, so do schools.
Wait-listed applicants might not find out until May or June, at the end of their senior year. Admissions officers say they use wait-listing because it is difficult to know which applicants really want to attend their school
