Courses

Each course is usually 16 weeks long and offered one time per year. Courses start in January, May and September.

Course Format and Schedule

Courses are self-paced, with weekly deadlines for activities such as reading, translation assignments and exams. You do not need to be online at a particular time to complete your course work.

The focus of the Translation Certificate courses is not on theoretical content. These are skills-based courses, whose goal is to facilitate acquisition of translation competence, more specifically the transfer component of competence. Given the short duration of the program (each course is only 16 weeks), we focus on core skills, which require rich feedback (from instructors and peers) and guided practice.

Unlike transfer competence, content (terminology, field specific knowledge) can be learned independently and through intensive specialized webinars, widely available in the field. Certificate courses teach content and terminology in the context of translation tasks (rather than as separate discrete units) and aim to teach students how to identify and remedy knowledge gaps (something they will have to do throughout their careers as translators).

The Translation Certificate courses are practical, workshop-style courses, as indicated on the syllabus. The assignments provide opportunities to learn (with purposely selected texts and guided activities to help students learn translation skills). Exams do not test content, but skills and thus, no preparatory materials are needed. Students prepare for exams throughout the entire course (through guided practice and feedback).

Application, Registration and Payment

To apply, you will need to complete and submit a background information form and a written entrance exam to test your proficiency in English and Portuguese. Applying to the program is free, and you can apply any time. Please allow 2 weeks before contacting us about the results of your application.

If you are accepted into the program, you will be notified when classes open for registration.

A payment plan is available for students registering for this program. Discounts are available for University of Arizona employees and military, as well as early registration (1 month before course start). Only one discount can be used per registration.

Please apply early (at least a month and a half before a course starts) if you would like to take advantage of the payment plan and/or other applicable discounts
