An Eagle Scout letter of recommendation is a letter written by an approved reference supporting a scout's advancement to the rank of Eagle Scout. A scout must list five to six references on his Eagle Scout application, and all must be contacted successfully prior to the review.
The Boy Scouts of America allows references to submit letters or be contacted through other means by the review board. Use of email is discouraged due to privacy concerns. Securing the letters of recommendation early ensures their timely receipt, thus avoiding any delays in the review and advancement of a member to Eagle Scout rank.
