A few ideas:<p>1) A public list of recognized job titles (think of an employment bureau catalog or else) that defines the job description by an authority. At least a reference that most would pay attention to.<p>2) A unified training program for each branch (or developers in question) outlining the required skills or targets for developers<p>3) A WordPress.org profile that showcases the work in a better manner - think of a GitHub&#x2F;LinkedIn version in the WordPress context<p>I also wouldn&#x27;t necessarily vouch for a licensing program (probably commercial&#x2F;financial interests), but some standardization and guidelines could help immensely and solve various problems for employers, clients, expert and beginner developers, site builders, even users.
