IRS Link & Learn Taxes: Training and Certification for Volunteer Tax Preparers
The Epsilon XR team developed Link & Learn Taxes for the IRS, an 80-hour web-based training program comprising over 4,000 pages of tax law narrative, examples, case studies, interview simulations, audio, and comprehensive exercises. Instructional support in the form of lesson plans, presentations, and a printed training guide are available for blended learning environments.
Link & Learn Taxes has been on the IRS website (http://www.irs.gov) and CD-ROM since 2004, and is available to volunteers and the public. During peak periods, more than 300,000 people visit Link & Learn Taxes; over 20 million pages have been viewed. There have been over 900,000 certifications using the online test and more volunteers are certified every year.
