A web developer creates websites and ensures they function reliably and efficiently. To perform those tasks, web developers need to be proficient in a variety of programming languages and show that proficiency to employers, co-workers, and themselves. The Tosa Web Developer industry-recognized certification provides exactly that.

The Tosa Web Developer certification determines and validates a candidate’s proficiency and skill level in HTML, CSS, and JavaScript for web development. The Tosa Web Developer certification supports students, trainees, employees, or jobseekers in their employment, professional, or academic objectives.

There are no eligibility requirements to take a Tosa certification exam. In K-12, we recommend using Tosa Web Developer certifications as part of a course or curriculum starting at grade 9.
