Networking Academy partners with Learning@Cisco to enable qualifying students to take CCENT and CCNA certification exams at a reduced cost.Discount Vouchers are available for the following Cisco Certification Exams ONLY:

• ICND1 (640-822)
• ICND2 (640-816)
• CCNA Composite (640-802)

To qualify for a discount voucher you must meet the following eligibility criteria:

Voucher eligible students may follow only one of these paths depending on what voucher eligible course they have just completed:

Networking Academy students who successfully meet the voucher eligibility requirements will qualify for a single discount voucher. Discount vouchers can only be used once. Since vouchers expire, students should not request a voucher until they are ready to take the exam. Voucher eligibility does not imply that a student will do well on the exam. Students should take the time to study and prepare prior to requesting a voucher.

When you become eligible for a Certification Exam discount voucher, a Request Voucher link will appear on your Academy Connection Home Page under Professional Development. After you are sure your instructor has passed you from the class, check your Home Page for the link. You are not eligible if the link does not appear.

For CCNA vouchers, students must complete all four courses of either CCNA Discovery or CCNA Exploration  and receive a score of 75 percent or higher on their first attempt of the final exam for the final CCNA Discovery course; Designing and Supporting Computer Networks, or for the final CCNA Exploration course; Accessing
the WAN.
