Python is an interpreted, object-oriented, high-level programming language with dynamic semantics that can be utilized to perform a wide variety of tasks. Python’s dynamic bindings, data structures, and ease of readability make it a very popular, and highly sought-after, programming language in today’s marketplace – especially for Rapid Application Development.

The Tosa Python 3 industry-recognized certification determines and validates a candidate’s proficiency and skill level in Python 3’s key features, such as algorithms, input/output management, import and export, context and use cases, data structures, and dynamic bindings. The Tosa Python 3 certification supports students, trainees, employees, or jobseekers in their employment, professional, or academic objectives.

There are no eligibility requirements to take a Tosa certification exam. In K-12, we recommend using Tosa Python 3 certifications as part of a course or curriculum starting at grade 9.

Available Badges for Python

Skill Domains Assessed

Language and syntax

The questions in this domain concern knowledge of the Python language and its syntax. The candidate is tested on their knowledge of the characteristics and specificities of the programming language, of its general features, and of its syntax.

Data structures and objects

This block of skills covers questions about objects in Python, and tests the candidate's ability to use and create built-in objects or objects created specifically for a problem, the creation and use of functions, and object-oriented programming features.

Modules and packages

The candidate is tested on their ability to create, import and use modules within a project. The questions will also cover the knowledge and ability to use the main modules of the standard library.

Code Optimization

This domain encompasses the skills and knowledge needed to create high-performance Python programs. Questions cover mastery of the performance of Python tools and functions, as well as the ability to recognize and reproduce simple algorithms to applied cases.

Certification Exam Detail

The Tosa Python Certification Exam relies on a database of more than 170 questions. It is composed of a mix of 35 questions, including multiple-choice, interactive questions, and live coding exercises, and lasts 90 minutes. The algorithm adapts to each answer of the candidates to adjust the difficulty level of the questions until they reach the exact definition of the candidates’ level by calculating the limit of their skills. Candidates receive a numeric score out of 1000 points associated to a proficiency level on a five-level scale. Candidates who score between 1 and 550 points don't earn the certification. They will not receive a diploma but a certificate of completion. Candidates who score 551 points or above earn the certification. They will receive a diploma by email within five (5) business days  and are eligible to receive a Credly digital badge.

The Tosa Python Certification Exam is valid for three (3) years. Once expired, earners must retake the certification to maintain it over time. Earners wishing to demonstrate skills development and personal growth may re-take the exam to improve their score at any time. There is no waiting period between two attempts.

Rules & Technical Requirements

Tosa certifications must be taken under specific proctoring conditions. For more information about Tosa certification exam rules and technical requirements, please visit our dedicated exam policies page or consult the downloadable PDFs below.

Prepare For Your Certification Exam

In order to be well prepared for your exam day, we recommend:

  • Taking at least one Tosa assessment test prior to your exam
    The Tosa assessment test, like the certification exam, is an adaptive test composed of a mix of multiple-choice, interactive, and live in-the-application questions. It contains 25 questions and lasts 40 minutes. It does not need to be taken under proctored conditions. Results are delivered on the same 1-to-5 proficiency level scale and includes detailed skills reports to help determine student or candidate strengths and weaknesses before taking the certification exam.
  • Utilizing the free practice tests available on our website
    In addition to our Tosa assessment tests, we offer short practice tests for free. Simply navigate to and click on the “Free practice test” button on the top right of the page, then select which test subject you’d like to practice.
  • Taking a Tosa-aligned course
    We have partnered with several eLearning providers and publishers to provide online courses that align with the Tosa certification objectives. To achieve a productive level or higher for a Tosa certification, it requires candidates an average of 150 hours of training and hands-on experience with Python. This average training time depends on their pre-existing skills or knowledge, the expected outcome for the certification (score/level), and the provider.
