Flexible Scheduling Options - We Make Going To School An Easy Fit In Your Life

You have the choice of taking class in person or online as part of a group during any of our 4 academic terms.  If group learning isn't your style, you can choose independent start online and begin your course anytime.

You choose how many courses you'd like to take - you must take at least one course per term, but you can take two or three courses at a time if that fits in your schedule.

Academic Calendar for Online Independent Start Anytime

NTI makes going to school easy with three course delivery types so you can make the choice that best fits your lifestyle and learning style.  Take full advantage of our flexible education system by choosing which format to take each time you register for a course.  You don't have to commit to one format - take some courses in person and others online; some as group start others as independent start - the choice is yours on a course-by-course basis.  Note: Most of our courses are available in all three formats; a few are online only and 2 courses are independent start only.
