JavaScript Coding Specialist (JCS)
BETA Certification

The JavaScript Coding Specialist Exam is an industry global recognised certification which grants coding specialists, web developers and designers the ability to validate their front-end and back-end web development skills. JavaScript is one of the most flexible and powerful programming languges implemented across the web allowing web designers and developers to build fluid interactive web pages. It is a popular language to learn because JavaScript is literally everywhere, unifying all web application development into one programming language.

What are the benefits of getting a JavaScript Certification?

The unique peculiarity of the JCS Certification is the assessment modality, which consists of a real live coding environment, offers candidates the ability to write proper code to perform task-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.

JavaScript was initially designed to make web pages come to life. The programs in this language are called scripts. It is one of the three main languages used and the most essential part of web application today. This 25-year-old programming language is listed as the first language to be learned by people who want to program because of its full-stack capabilities, it can be used as both a frontend and backend programming language.

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 JSC 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.

I am a business leader and I have a company in finance. We need very often to hire developers with Python or Javascript skills as development is an active part of our business; we need to improve continuously the stability and quality of our system, so we need people with experience. We receive between 500 and 1500 applications when we create a job post. One of the very first things we do is shortlist applications, by looking for specific words or certifications that can prove candidates have what we need.

Unfortunately, 2 out 3 candidates, even if certified, don’t seem to own quality skills and their knowledge seem to be more theoretical. KP certifications solve that issue, because now we know, in advance, that a candidate possessing those credentials must also own the knowledge in a practical way. KP significantly contribute to addressing and providing a solution to the skills gap in the modern world.
