To receive a web design certificate, students must complete a final portfolio project using the skills learned throughout the course, such as HTML, Photoshop, and JavaScript. The portfolio site must contain at least 10 pages demonstrating the student's abilities and include elements like biographical information, resume, graphics, and services offered. Students are also required to submit a site plan, test their site on different browsers, and choose a potential domain name for their future web design business. The portfolio site will serve as a way for students to showcase their talents to potential employers in the web design field.
