CHECK accreditation - the highest standards for security testing
We provide accreditations recognised by NCSC for individuals providing technical security services for the CHECK scheme. These rigorous exams demonstrate the highest levels of knowledge, skill and competence. To ensure relevancy of knowledge within this often-changing environment the certification process is repeated every three years.
Our CSTM and CSTL exams are led by NCSC approved Assessors who hold CHECK TEAM LEADER Qualifications for Infrastructure and Web Applications.
Exam FAQs
Passing an exam with The Cyber Scheme is one of the mandatory assurance checks undertaken by the National Cyber Security Centre (NCSC) before CHECK Team Member or Leader Status can be awarded. The Cyber Scheme cannot award CHECK status, but do award certificates recognised by NCSC as confirmation that the necessary technical standard for CHECK has been met.
CTM = CHECK Team Member, the term applied by NCSC
The CSTM exam you take with The Cyber Scheme = Cyber Scheme Team Member. The terms are essentially interchangeable, with CSTM being the brand name for our CTM-level exam.
CTL = CHECK Team Leader, the term applied by NCSC
The CSTL exam you take with The Cyber Scheme = Cyber Scheme Team Leader. The terms are essentially interchangeable, with CSTL being the brand name for our CTL-level exam.
We offer two CTL-level exams, CSTL-INF (Infrastructure) and CSTL-Web App (Web Applications). There are no requirements for a pass in one exam before taking another; if you have any questions about your readiness to take an exam please get in touch.
The Cyber Scheme is one of only two organisations accredited by NCSC to offer examinations that meet UK Government Standards in Penetration Testing.
The NCSC, as the National Authority for Cyber Security ensures that the Cyber Scheme is operating at the highest standards in the delivery of our training and examinations. Certifications issued by the Cyber Scheme are therefore recognised by NCSC as meeting the necessary standards to apply for membership of the NCSC CHECK scheme.
Quality of service delivery is subject to regular audit and is monitored on an on-going basis by the NCSC. This ensures that course content reflects the current cyber security trends and threats and that the examination processes are robust and as near real world as is possible in an examination environment.
For the Cyber Scheme Team Leader (CSTL) certification we have developed a testing environment that provides near real world challenges for candidates through randomly generated scenarios, meaning no two candidates will ever sit the same test. Successful candidates and future employers can therefore be assured that the certification has fully tested the candidate’s knowledge, experience and creative thinking within the world of penetration testing.

“I can honestly say that the CSTM exam was head and shoulders above the exam I sat 3 years ago. Both in terms of the exam content and the exam invigilators. The “open book” nature of the practical exam was a breath of fresh air, and the theory side was fair and certainly more “modern” than others I have experienced”.
CSTM Candidate
“This was my first interaction with The Cyber Scheme and it was a very positive experience. The booking was easy, the communication from the staff was great and any queries were quickly answered and resolved. On the day the assessors were very clear on the rules, scoping and expectations. The scoping and interview aspects were handled really well, and it is reassuring to know that the assessors understand what is required and have a higher level of technical knowledge than the candidates.”

Neurodiversity and Special Needs
The Cyber Scheme believe everyone should have access to a career in security testing. We will make allowances (where possible) for any candidate who requires special support during training and examinations.
These allowances are to ensure you are given an equal opportunity to demonstrate the necessary skills and competence required and will be dependent on the nature of the condition. Each request will be dealt with on an individual basis.
Access to all of our facilities is suitable for people with mobility problems. Should any other special facilities be required please get in touch at time of booking. We will need to see supporting documentation around the condition. No information will be retained or stored once the request is validated.
The Cyber Scheme will assess if any of the needs fundamentally undermine the quality of the examination. Reasonable accommodations are made for candidates who:
- have a physical or mental impairment that substantially limits that person in one or more major life activities (e.g. walking, talking, hearing and performing manual tasks;
- have a record of such a physical or mental impairment; or
- are regarded as having a physical or mental impairment.
In order for any accommodation to be endorsed, a candidate must submit a written request accompanied by supporting documentation on official letter head from their health care provider that explains the nature of the disability or condition and specifies the exact accommodation(s) needed. Please contact us for help with submitting this information.
