The CCT INF examination also covers a common set of core skills and knowledge, and is available to take in Pearson VUE Test Centres globally.
IMPORTANT: new CCT INF exam
This new CCT INF exam, introduced in 2024, includes a revised syllabus issued in January 2024. Please ensure you refer to the appropriate syllabus when preparing for the exam.

Exam format
The new CCT INF exam has two distinct parts:
– A written exam which is made of two components: a multiple-choice test and a written scenario
– A practical exam
The multiple–choice component tests a candidates’ knowledge of the subject areas and the scenario assesses a candidates’ risk analysis and report writing skills.
The practical component tests candidates’ hands-on penetration testing methodology and skills against reference networks, hosts and applications. Candidates will not be able to use their own laptops and therefore will not able to access their own tooling. A version of Kali Linux will be available within the practical exam environment to address the practical assessment.
Previously, candidates had to take and pass the written exam before being able to take the practical exam. In the new exam, candidates may take the exams in any order.

There is also more focus on cloud services and security where six new skills have been introduced. Network intrusion protection, Unix exploitation and NoSQL injection are also amongst the areas with new skills. The new exam also builds on the existing soft skills and assessment management section introducing global and regional law and compliance components and report quality assurance.

The written scenario component is part of the written CCT INF exam which also includes a multiple-choice test.
The scenario essentially assesses the candidate’s knowledge and ability to write reports. There are also elements related to scoping engagements, assessing risks inherent to their findings and composing an issues’ write up for a report. Candidates could also be expected to demonstrate an understanding of relevant legislation affecting penetration testing in their operating jurisdiction.
Format
The written component starts after candidates have submitted their answers to the multiple-choice component within their written exam. They will be given 15 minutes before the scenario examination starts to read through the requirements and no examination activities are permitted during this time.
Once the written scenario starts, candidates will need to answer long form questions and will be given 120 minutes to do so. There is no requirement to complete each question in the order that they are presented meaning that candidates are free to complete them as they wish, provided that they do so within the allotted time.
Reminder: candidates must achieve the minimum pass mark in both the multiple-choice and written scenario parts to pass their written exam.
Marking
The written scenario is manually marked by CREST Assessors. The total marks on this section is 120 marks.
Sample scenario
You can read our sample scenario document online, which contains useful and sample information related to the CREST Certified Tester (CCT) examination scenario component.
