  1. Determine which courses are right for you since most TEL Library courses are offered via 3 different methods.
    • College Credit Courses:  These courses are traditional graded courses that can be transfered for college credit.  Students will earn a grade that will be on their official TEL Library transcript. These courses require that students have a photo ID to complete the mid-term, final and obtain a transcript.  Please note, you do not need to purchase a textbook in addition to the course.
      The grade for these courses is based upon:

      • Participation and completion of each lesson = 10% of the final grade
      • Graded module quizzes = 15% of the final grade
      • Graded module evidence activities = 25% of the final grade
      • Graded proctored mid-term examination = 25% of the final grade
      • Graded proctored final examination = 25% of the final grade
    • Certificate Courses:  These courses contain all of the same learning content as the College Credit Courses, but do not require the completion of evidence activities, and midterm and final examinations. The outcome for participants is a TEL library Certificate of Completion and publicly sharable Badge. Please note, you do not need to purchase a textbook in addition to the course.
      To be eligible for full course completion, participants must:

      • Complete each lesson, including the Check Your Knowledge activity.
      • Obtain a grade of 80% or higher on the module quizzes.  Each participant is given 3 attempts to reach this grade.

      Participants will not be required to complete or have access to evidence activities, mid-term or final examinations.

    • Textbooks: TEL Library Textbooks contain all of the same learning content of the College Credit Courses, but do not include any formal assessment activities.  Purchasers can complete the lesson activities, but no points, grade or certifications will be tracked or awarded.

Start Learning!

  • Login to your TEL Library account
  • Find and purchase courses on our catalog page.
  • College Credit and Certificate courses are self-paced and you can complete them on your schedule.  We suggest that you follow either the 7 or 14 week schedules included on the Course Documents Tab.
