Dear ASDP Board

Certification Programs

The Master Sewing and Design Professional (MSDP) and Master Alteration Specialist (MAS) Certification Programs are performance-based programs that were developed by the Association of Sewing and Design Professionals (ASDP). They are based on ASDP's Standards of Quality and open to anyone with a sewing-related business. MSDP and MAS certification provides the professional with the prestigious credentials that validate skills and expertise.


The Apprentice Program Qualified (“APQ”) Designation is a way to qualify your skills to meet the requirements to take on apprentices utilizing the Department of Labor (“DoL”) National Guideline Standards (“NGS”) Standard Alterations Technician (“SAT”) program developed by the Association of Sewing and Design Professionals (“ASDP”). The APQ designation is for experienced alteration specialists. Once skills are demonstrated, the designation is granted. Skills are demonstrated by the completion of the Alteration Techniques, Alteration Fit, and Fabrics modules of the Master Alteration Specialist (“MAS”) Program.
