FOA Specialist Certifications
For those who already have a first level FOA certification (CFOT or CPCT) and wish to pursue the rewards and recognition of higher level certifications, the FOA offers specialist certifications in Outside Plant Installation, Fiber Optic Network Design, FTTx, Termination, Splicing and Testing. The CFOS designation is for advanced, well-trained, experienced fiber optic technicians, thus the requirements for these certifications are more stringent than those for the CFOT or CPCT. There are two different paths for CFOS certification, direct or training, described below.
All FOA CFOS Certifications Require:
- Current first level certification (CFOT or CPCT as required for the specific CFOS certification)
- Relevant field experience as documented by your CFOT logbook and/or training courses from FOA-Approved schools, manufacturers or others
- Passing a Specialist certification exam
The FOA Online Fiber Optic Reference Guide, the FOA textbooks or self-study programs on Fiber U are recommended for preparation for the exams.
If you are already a CFOT or CPCT interested in specialist certifications, you should log your field experience in a FOA logbook. Download a FOA Logbook (pdf file) to keep records of your experience and training from vendors, other sources and/or from a FOA-approved school.
When you think you meet the FOA requirements, contact the FOA for information on taking the specialist certification exams. Local test proctoring is available at FOA approved training centers or may be arranged by the individual. Application for CFOS Certification (pdf)
Note: With any of the specialist certifications, you do not get a new CFOT/Membership number. Upon completion of the requirements, you will receive a new FOA ID Card with your new certifications listed. Your CFOT number and expiration data will not change.

FOA Specialist Certification FAQs
Is there one exam for all specialties?
No. Each specialty has its own requirements and exam. You can take one of them or all of them, depending on which you qualify for.
What is the cost?
The fee for applying directly to the FOA for specialist exams is listed on the application form.
Do you have to be a CFOT or CPCT to take the specialist tests?
Yes, you must have already passed the first level certification exam (CFOT, CPCT) and you must be a FOA member in good standing.
What experience level is needed and how do I provide documentation for that experience?
You must have at least the experience level required by the specialty for which you apply to take the exam. Experience can be either specialist training that meets the requirements or actual installation experience, as documented by your CFOT logbook. This is a form you can download from the FOA website and print. Manufacturer's training will be considered as partial experience to qualify for the certification.
Studying For FOA Certification Exams
If you are preparing for a FOA exam, either taking a course from an FOA-approved school, you can study for the exam using the FOA " Fiber U" self study programs. These self-study programs use online references from the FOA websites to guide you through reading material and watching videos, then taking quizzes which should prepare you for the FOA exams.
Do I send the FOA my logbook to verify my experience?
NO. Send only a copy of the logbook to the FOA office- keep the original in your possession.
How do I take the exam?
You must pass a comprehensive exam that will be proctored. Exams can be taken on paper or online. Like the CFOT exam, the specialist exams are closed book exams. You should make arrangements to have the exam proctored by your supervisor, instructor or teacher or other professional. It may not be a co-worker or relative. This person must verify that you took the exam without assistance from other people or reference materials during the specified time interval.
You fill in the CFOS Application and send to the FOA with a copy of your CFOT Logbook.
Be sure to look over the qualifications carefully - you need to have extensive experience to qualify for each of these three certifications.
The third page should be filled out by the person you have chosen to be your Proctor. Then send or fax it back to the FOA for approval. After verification that applicant meets the requirements, the test will be sent to the Proctor. It will be this person's responsibility to oversee you taking the test, collect the test and mail it back to the FOA.
