The IRS requires the district to have a written Plan Document with a list of approved vendors. The district has to administer its program but must do so within reason and also comply with the open vendor law discussed at the conference (Insurance Code Section 770.3) There may be administrative reasons that permit the district to eliminate vendors. Changing the list of approved vendors by deselecting vendors may create challenges for participants. Contact the district to ask them about the list of approved vendors. If you are not satisfied, contact your local chapter president or your local CTA office and speak to your Primary Contact Staff or CTA UniSERV Director .
