In addition to the regular semester-long classes, Johnson also offers seven-week classes that take place during the first or second half of each term. For the fall term, first half classes run from August to mid-October; second-half classes run from mid-October through December. For the spring term, first-half classes begin in January and end in mid-March; second-half classes start in mid-March and end in May. Johnson also has week long class offerings in early January, before the University’s official start of Spring classes.
