We work hard to keep costs as low as possible, but in order to remain financially sustainable, we have to consider the realities of rising costs. It’s been more than a decade since we’ve made comprehensive changes to our professional development offerings. We’re doing so now to make sure that what we’re charging for our courses reflects their value in the field, and to ensure that instructors are compensated fairly.

Our new pricing structure takes effect July 1, 2024, and will reflect a direct relationship between the number of contact hours and the cost of the course. Please note that all Interpretive Host courses include a certificate upon completion.
