C# Coding Apprentice

Validate your fundamental C# coding skills, prove that you can work with .NET Classes, Design Patterns, Identifiers, Data Types and LINQ. This certification exam was designed for junior coders. C# coding skills are valuable for building almost any type of application whether it be for web, console, windows, mobile or desktop. This certification is a great first step toward a lucrative career in software development. 

What are the benefits of getting a C# Coding Apprentice Certification?

The CSCA is a globally recognized industry certification that validates fundamental C# coding skills. This certification grants school students, aspiring coders, junior software developers, and IT professionals the ability to assess their knowledge and get credentials for their programming skills.

This introductory exam was designed for junior coders who are coding for the first time but are eager to test their capabilities and prove their skills. As with the C# Coding Specialist exam this assessment modality consists of a real live coding environment, combined with Parsons programming puzzles, drag-and-drop matching question type and multiple-choice question type.

If you are in the process of learning how to write basic scripts, working with basic C# syntax, variables, functions or data types then this exam is the best way to validate that you have obtained the necessary knowledge to put those skills to work.

Exam Objective Domains

Candidates are expected to demonstrate a general background in coding with C#. Prior to taking the exam, a candidate is expected to have approximately 100 hours of hands-on experience or lectures on developing using C#.

The elevated level of preparation required is derived from the industry-standard level of the exam and the fact that this certification reflects the candidate’s readiness to enter the job market. Moreover, this Certification is used as a job placement index by recruiting managers, for the correct placement of a job seeker. Knowledge Pillars CSCA uses a task-based format in order to ensure the validity of the results.

To optimize the examination experience for the Candidate, Knowledge Pillars has taken certain steps to utilize a real C# coding environment during the examination. The exam is provided both in Testing Centers or remotely, via the remote proctoring system.

    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 CCA 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.
