Python Coding Specialist (PCS) is the new frontier of programming certification!

The PCS is a globally-recognized industry certification on Python programming, which grants coding specialists, software developers, and IT professionals the ability to assess their knowledge and get credentials for their programming skills.

The unique peculiarity of the PCS 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 with this very advanced assessment solution.

PCS is part of a larger set of certifications’ level, which will all go live in the next few months.

  • PCE – The highest level of expertise for the Python Coding Certification. Candidates must have at least 2 years’ programming experience to pass this exam.
  • PCS – The intermediate level of the Certification. Students taking this exam have generally a good but quite basic understanding of coding with Python and are generally at the beginning of their development career or are still at colleges.
  • PCP – The very basic and entry level module of the Certification. Candidates taking this exam have very little or no experience on programming and are generally students at school.

What is Python?

Python is an interpreted, high-level, object-oriented general purpose programming language. It’s one of the most popular programming languages on the planet, adopted by and adapted for every sector and industry – from finance, to medicine, to gaming.

Since its creation, Python has grown exponentially; nowadays, it has become the most used coding language by far.

Nowadays Python ranks 1st in the PYPL Index Popularity Rate.

More about Python

First and foremost reason why Python is much popular because it is highly productive as compared to other programming languages like C++ and Java. It is much more concise and expressive language and requires less time, effort, and lines of code to perform the same operations.

The Python features like one-liners and dynamic type system allow developers to write very fewer lines of code for tasks that require more lines of code in other languages. This makes Python very easy-to-learn programming language even for beginners and newbies. For instance, Python programs are slower than Java, but they also take very less time to develop, as Python codes are 3 to 5 times shorter than Java codes.

Python is also very famous for its simple programming syntax, code readability and English-like commands that make coding in Python lot easier and efficient.

We can see something written in Python every day and almost everywhere.

It’s used extensively to implement complex Internet services like search engines, cloud storage and tools, social media and so on. 

Many developing tools are implemented in Python.

Lots of IT project testers have started using Python to carry out repeatable test procedures. 

Python is often used for:

  • Web and Internet development
  • Scientific and numeric computing
  • Desktop GUIs
  • Software Development
  • Business applications
  • Games
  • Websites services

According to Indeed, the average Python programmer salary in the US in 2020 is $120,365 per year. New York, California and Washington DC are the top 3 best-paid states for Python developers.

Python developers are in high demand – not only because the language is so popular and widely used but mostly due to the fact that Python became a solution in many different areas.

A simple job research on Indeed shows that there are over 20,000 published job adverts per week looking for Python Programmers.

Recent studies show this demand will keep growing.

Passing score: 75%

Format: Linear and In-App

The examination procedure

  1. The students will have to answer all the question within the given timeframe.
  2. 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 45 minutes timeframe).
  3. All unanswered questions will be marked as incorrect.
  4. When the test finishes the result of the examination is sent to KP’s server for storing.

The minimum system requirements are:

  • Operating system: Windows 7/8/10 OS, MacOS X 10.0x or newer, Linux OS
  • Minimum RAM: 1GB or more depending on the Operating System
  • Minimum processor: 1.0 Ghz or more depending on the operating system and the architecture
  • A color monitor with minimum display resolution: 1366px by 768px
  • Access to the internet
  • Latest version of Chrome browser
  • Automatic updates, notifications, other popup windows and anything that can disrupt the examination process should be disabled

Candidates are expected to demonstrate a firm background at developing and debugging simple programs using Python. Prior to taking the exam, a candidate is expected to have approximately 150 hours of hands-on experience or lectures on developing using Python.

The elevated level of preparation required is derived by 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 PCS use 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 real Python environment during the examination, as well as to ensure stable experience for the examinées. The exam is provided both in Testing Centers, or remotely, via the remote proctoring system.
