It can easily be the start of a career in interior design or an in-depth way to gain the skills and experience for personal projects. 

This course costs about $1,000–dependent on current incentives and offers. You can also select a payment plan that brings the cost to about $50 per week. You’ll be encouraged to spend about four to six hours per week on the course material. If you do, you can expect to finish in 24 weeks. However, you’ll have up to one year to complete the course. After that, you’ll need to purchase an extension if you want to lengthen your enrollment.

If you opt for this type of a la carte education, note that you won’t have the feedback of an instructor when it comes to assignments or projects.

The advantage of signing up for a course is the opportunity to systematically learn the basic principles of design. Whether your goal is to become more proficient in decorating your own space or to explore a career in interior design, these online learning programs have been useful to many students. 

In addition, many interior design courses offer a tutor or mentor who is an active professional in the field.

What Should I Look for in an Online Interior Design Course?

Establish what you want to learn before deciding on an interior design course. Are you most interested in understanding interior design styles? Selecting furniture that is right for a room?

Your answers to these and similar questions can guide you in what to look for when evaluating an interior design course. Look through the course outline or prospectus to understand what the units, lessons, or classes cover.

Many online interior design programs are also accredited by one or more organizations. These accreditations may relate to the quality of content, the online education experience, or customer satisfaction.
