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.

Prepare For Your Certification Exam

In order to be well prepared for your exam day, we recommend:

• Taking at least one Tosa assessment test prior to your exam
  The Tosa assessment test, like the certification exam, is an adaptive test composed of a mix of multiple-choice, interactive, and live in-the-application questions. It contains 25 questions and lasts 40 minutes. It does not need to be taken under proctored conditions. Results are delivered on the same 1-to-5 proficiency level scale and includes detailed skills reports to help determine student or candidate strengths and weaknesses before taking the certification exam.
• Utilizing the free practice tests available on our website
  In addition to our Tosa assessment tests, we offer short practice tests for free. Simply navigate to and click on the “Free practice test” button on the top right of the page, then select which test subject you’d like to practice.
• Taking a Tosa-aligned course
  We have partnered with several eLearning providers and publishers to provide online courses that align with the Tosa certification objectives. To achieve a productive level or higher for a Tosa certification, it requires candidates an average of 150 hours of training and hands-on experience with HTML, JavaScript and CSS. This average training time depends on their pre-existing skills or knowledge, the expected outcome for the certification (score/level), and the provider.
