Slightly more than half of nearly 300 college presidents surveyed in September by the American Council on Education (ACE) say their campuses' enrollment is lower this fall than a year ago, with community college executives reporting decreases the most. Thirty-one percent of private four-year college presidents said they enrolled more students this fall, compared to 15% of public four-year and 10% of public two-year leaders. Some 70% of four-year college execs reported decreased international student enrollment.
