Although two-thirds of American high school graduates go on to study in college, recent highs chool graduates no longer dominate the college campuses. Adults of all ages return to the classroom, either for new vocational skills or for personal growth. In 1966, for example, almost 20% of American college students were over age 35. Some 500,000 college students are over 50. American faith in the value of education is exemplified by the rising number of Americans who have at least a bachelor's de-gree. Almost one-quarter of Americans over age 25 are college graduates. College attendance is not re-served for the wealthy and the academically talented. It is available to anyone who wants to go. Right now about 15 million students are taking advantage of the opportunity. For those not academically pre-pared to handle college-level work, about 80% of undergraduate schools offer remedial (sometimes called developmental)classes in reading, writing and math.
The U. S. has about 3,700 institutions of higher learning. About 1,600 of these are 2-yearschools. More than 2,000 are 4-year schools, many of which also have graduate programs. With so many colleges to choose from, how do prospective students find the right one for their needs? Information about schools is easy to obtain. Students can write for printed information and applications. Some schools even mail out video. Students can also use computer programs that allow them to specify particular interests and print out a list of schools that fit their description. Most institutions of higher learning also have web sites. Many schools send college representatives to high schools and two-year colleges to recruit students. Finally, many students visit colleges, take tours of campuses, and talk to counselors.
