C# Coding Specialist Certification
C# is a general-purpose, multi-paradigm programming language encompassing static typing, strong typing, lexically scoped, imperative, declarative, functional, generic, object-oriented, and component-oriented programming disciplines.
The CSCS is a globally-recognized industry certification on C# programming, which grants coding specialists, software developers or engineers, game developers and IT professionals the ability to assess their knowledge and get credentials for their programming skills.
The unique peculiarity of the CSCS Certification is the assessment modality, which consists of a real live coding environment, offers candidates the ability to write proper code to perform tasks-based questions. This technology is called LITA (Live in the Application) and Knowledge Pillars is one of the very few organizations able to provide this very advanced assessment solution.
C# is highly versatile, and can be used to create a ton of projects, including but not limited to mobile apps, cloud-based services, enterprise software, and games. Lots and lots of games. It’s widely used in game development.
Number of questions: 35
Time limit: 50 minutes
Passing score: 75%
Format: Linear and Live-in-the-App
The examination procedure
The students will have to answer all the question within the given timeframe.
They are free to ignore as many questions as they want. They will have the option to flag the questions and then review them at the end of the test (within the 50 minutes timeframe). All unanswered questions will be marked as incorrect. When the test finishes the result of the examination is sent to KP’s server for storing. Exam results are sent to candidates within 72 hours.

Participating in BETA Exams
A critical part of the exam development process is the beta exam. By taking the exam in its beta format, candidates provide us with useful information to evaluate the technical accuracy, relevance, and psychometric characteristics of the questions before we score examinees.
Get 80% off the CSCS beta exam. If you take the beta exam, Knowledge Pillars will send a 25% discount voucher to the same email that you use to register for exams AFTER the beta exam has been scored. You can apply that voucher to your next Knowledge Pillars exam registration.
Note Participation in the beta is on a first come, first served basis. Due to popular demand, we recommend that you register as soon as the beta registration period begins.
Candidates located in China, India, Pakistan, or Turkey are not eligible to participate in beta exams for security reasons.
Preparing for a beta exam
You will have access to the Exam Details page that lists the skills that will be assessed on the exam. Knowledge Pillars does not currently offer training materials for its exams.
People interested in beta exams usually have access to other resources, are experienced with the technology, or work with the beta product. We recommend that you consult peers, community resources, and early-adopter articles for support if you need additional preparation materials.
Beta exam scoring and results
When you complete a beta exam, you do not receive a score immediately because the scoring model for the exam is not yet finalized.
You usually receive your exam score within 2-3 weeks after the exam becomes available worldwide—this can be up to 16 weeks after you take the exam, depending on when in the beta period you took the exam. This time frame reflects the comprehensive process used to evaluate the beta exam results, including statistically analyzing the data to evaluate the performance of each question and reading and evaluating all comments provided during the beta exam. The rescore process starts on the day that exams go live, and final scores are released approximately 10 days later.
Note Participation in beta exams is voluntary, and Knowledge Pillars makes no promises or guarantees regarding the beta exam process, availability of your scores, or the timing of your results. Generally online proctored exam results are presented within 72 hours.
Passing the beta exam
Passing a beta exam in your certification exam counts toward your transcript. You do not need to retake the exam in its final version and you will receive a digital badge as confirmation of your passing score. Make sure that you take another exam within a year so you can take advantage of the 25% discount you earned for taking the beta exam through our beta exam discount program.
If you do not pass the beta exam, you cannot retake the beta exam. If you are interested in earning a certification that requires successful completion of that exam, you must wait to retake the exam at regular cost when it’s live, or you can apply the 25% discount that you received for taking the beta exam through our beta exam discount program.
