Salesmanship combines both science and art. The art requires practice and application of correct methods, and the plans reflect a science of interactions. Of course, natural skills and inborn talent help, but study and a solid professional interest are essential. This shows that salesmanship is art-science based.

While not appropriate for every position, candidates for sales positions can stand out by becoming certified professional salespeople. This demonstrates competence in a well-known sales philosophy and that the holder has learned how to improve their sales abilities from an expert.

The National Association of Sales Professionals (NASP) offers a six-week online training course to those interested in advancing their sales profession. When you spend a lot of time around salespeople, their differences stand out. The best salespeople are proud of their skills. They recognize how many different professional areas of focus are needed to be good at sales. These are the kind of people who take the additional steps during their careers to learn all they can. Certification is natural for the professional salesperson.
