As is true of every skill or calling, even the most seasoned accessibility professional was once a novice. If you are considering a career in accessibility or have interest in being a leader in advancing accessibility initiatives from whatever role you're in, you might already be an accessibility champion in the making.
You might be an accessibility champion if you:
Respect the process but value results even more. Checking boxes is important, but if the culmination of everyone's efforts isn't improved accessibility, the process fell short.
Creatively apply knowledge to solve problems. Some accessibility checkpoints and best practices are cut-and-dry, and some necessarily require interpretation for effective application.
Have an aptitude for technical concepts, but an appetite for making things better for people. Accessibility is about removing barriers for people, bridging unnecessary divides — the technical piece is the vehicle that gets us there.
Know you're never done learning. No amount of training (or really enjoyable blog articles) can replace valuable experience, and technology is ever-advancing, so a commitment to accessibility is a commitment to continuous improvement and evolution.
Are willing to defend an unpopular opinion. Not everyone will agree with every recommendation, and seemingly-competing priorities like a tight timeline or a fixed budget can lead to compromises — but accessibility can't be one of those compromises.
