How many universities offer instructional design degrees?

There's no definitive, publicly accessible database that tracks *every* university worldwide offering instructional design degrees. The number is also constantly changing as programs are added and removed.

However, a quick search on sites like Peterson's, US News & World Report (for US-based programs), and various university directories will reveal that hundreds of universities worldwide offer instructional design degrees, certificates, or related programs at various levels (associate's, bachelor's, master's, doctorate). The exact number is impossible to state with precision.
