I got this from the ptcb.org website:
"When Do I receive my Results?
Your official score report will be mailed from PES within three (3) weeks of your examination date. PTCB, PES and Pearson VUE are unable to provide scores by telephone, email or fax. Candidates who do not receive the score report within 30 days after their examination date should contact PES and a duplicate score report will be issued at no cost. Requests for duplicate score reports should be sent to:
Professional Examination Service
475 Riverside Drive
New York, NY 10115
Requests for duplicate score reports received more than nienty (90) days after the examination date will require a $25 processing fee in the form of a check or money order. Please contact PES for more information."
