When COVID-19 closed Ukraine’s schools in 2020, the state government chose Prozori Solutions to build the country’s first national e-learning platform and mobile app: the All-Ukrainian Online School (“Vseukrainska Shkola Online” — VSO).
Built in cooperation with the Ministry of Education and Science of Ukraine, the Ministry of Digital Transformation of Ukraine, NGO Osvitoria, the Ukrainian Institute of Education Development (UIED), and Switzerland’s DECIDE project, VSO has grown into permanent national infrastructure, still central to Ukraine’s education system through Russia’s full-scale invasion since 24 February 2022.
Tasks
To provide equal and free access to quality educational content in Ukrainian (lessons, videos, tests, and methodological materials), that corresponds to the state program.
To provide Ukrainian learners and teachers the opportunity to study online, especially during quarantine measures.
To develop a modern eLearning mobile application
To do this, deploy a modern government educational platform for distance and blended earning for learners in grades 5-11 and to form reporting documentation on learning outcomes.
Challenges
Provide high security of the national platform.
Provide high bandwidth of the platform (hundreds of thousands of users).
Provide the most intuitive interface for teachers’ managing courses, so that would be no need for their training (consider the relationship of roles).
Create optimal solutions so that each teacher in the country could lead the course, invite and monitor the progress of learners in their grades.
Solutions
As it is irrelevant to teach a huge number of teachers in a short time to create courses through the administrative panel in the STUDIO, it was decided to transfer part of the functionality directly to the LMS, creating a platform “Teacher’s Office”. They can one-time duplicate ready-made “reference courses” to create their own course in the Studio, and track progress in LMS.
This provided methodological support to teachers who received modern materials (videos, PDF lessons, tests, etc.) approved by the state program, and an intuitive system for online learning of their learners.
Instructor of master courses
methodologists VSO who can create reference courses in the STUDIO and have advanced course management functionality
Learner
- register in LMS
- view the catalog of courses (separately master courses from VSO and courses from teachers)
- take courses
- view own progress
The teacher
- register in STUDIO for duplicate and edit “master courses”
- get access to the “Teacher’s Office” in LMS, where they can:
- 1. invite learners
- 2. track the success
- 3. review the journal of grades and reports of their course
- 4. send emails to students registered on their own course
- 5. organize discussions
Administrator
full functionality from all courses
Conducted a detailed analysis of infrastructure, functional and non-functional requirements, determined the software and hardware architecture of the solution, the requirements for system design.
Determined that the best solution would be to use Open edX with customizations.
Developed a platform in accordance with the requirements of the terms of reference, conducted internal testing of the system. Localization in the Ukrainian. Convenient, pleasant, and clear interface.
The platform consists of:
1. LMS — to provide online learning
(Registration page, login page, main page, course catalog, course categories, course, admin panel, journal of assessments, glossary, bookmarks, module for mailing to registered users)
2. Studio — to provide content for online learning
(Registration page, login page, course categories (class and subject), course creation and editing page, media files, system setup module, schedule and details, pages (sections on the horizontal panel), textbooks, certificate)
3. Preview — to provide testing of educational content
The Preview subsystem has the same appearance as the LMS subsystem. The subsystem is used to test the course and its content by teachers and instructors. The Preview subsystem has no other functionality. The subsystem is accessed by an administrator, a master course instructor, and a teacher.
Prozori Solutions built and launched the platform in four months — August to December 2020 — with no earlier platform to start from. Lesson content came from NGO Osvitoria: first as television broadcasts, then as video within the platform itself. By the start of the 2021–2022 school year, 1,800 lessons across 18 subjects were available.
Provided source code and compiled modules, database models, description of platform architecture, user guide, project management report, and other data and documents.
Provided technical support:
- Ensured compliance with the requirements for the protection of information in the system.
- Provided advice during the deployment of the solution in order to launch the system into experimental and industrial operation.
- Provides support for both the client and the users of the platform.
- Ensuring maximum data processing speed. Automatic scaling provides system flexibility.
- The role of construction design instructors was performed by the Prozori Solutions team (10 instructors).
- 90% of Ukrainian learners use smartphones for remote learning, 75% of users of National eLearning platform use smartphones.
- It was first developed on Android, as it is used by more than 80% of users of the platform.
- Ukrainian Mobile operators provide their users with free access to the mobile Internet
- It has access to all courses and materials posted on the platform. Learners can also participate in discussions and communicate with their classmates.

Results
The platform holds intense loads and successfully provides distance learning during quarantine activities and online mode of all Ukrainian schools.
About 200,000 users are registered in the first months. The system provides support for more than 10 thousand users simultaneously. Today, in 2026, the platform is used by more than 1,000,000 people.
Provides learners with video units, materials, tests, and the ability to track their progress. Helps in quarantine and in the classroom, to prepare homework and for exams, repetition of topics, and consolidation of the material.
Customizations created for course segmentation in the learner dashboard (reference “master courses” and courses from teachers)
The functionality of the platform and mob app will be constantly improved and expanded, which allows teachers to adapt teaching materials to the individual needs of their learners.
“The popularity of the platform and the feedback of learners and teachers about the high quality of lessons at the Nation-wide Online School inspire continued digitalization of Ukrainian education”.
Valeria Ionan, Deputy Minister of Digital Transformation for European Integration (2019–2025)
The platform provided free access to educational content in Ukrainian for children and teachers who live in the temporarily occupied territories of Ukraine or are abroad but want to study under the Ukrainian state program.
“The experience of leading countries in the digitalization of education, such as Estonia or China, shows that the availability of such national online platforms not only overcomes the limitations of the educational process during a pandemic. But is also a mandatory part of the educational space that helps children and teachers in teaching and learning, as well as increases the level of acquired knowledge”.
Government of Ukraine
Provides teachers with the necessary methodological guidelines and modern educational technologies.
Customizations have been created for advanced course administration capabilities directly from the Open edX LMS.
“The introduction of information and communication technologies expands the capabilities of teachers and forms the technological competencies of learners. This is one of the components of the Ukrainian school reform. That is why the Nation-wide Online School platform is an extremely valuable educational product”
Vadym Karandiy, Director of the Ukrainian Institute for Educational Development
An official open resource has been created, which unites all high-quality, modern educational content in Ukrainian that has passed the government’s review and met state educational standards.
The platform has strengthened inclusive education in the country. UNICEF Ukraine provides expert support for an inclusive project (sign language translation, audio description tracks).
Prozori Solutions is ready to support further initiatives.
Due to the mobile application, official public education in the online format has become even more convenient and accessible.
75% of platform users access VSO via smartphone. The Android-first mobile app remains free to use, thanks to zero-rated data agreements with Ukrainian mobile operators — critical when home internet access became unreliable during the war.
Provides government agencies with global statistics and reports on learner performance on a variety of topics and school subjects.
The national platform was successfully launched and presented by the Ukrainian government on December 11, 2020. It will be able to be used constantly, not only during quarantine.
“In the context of a pandemic COVID-19, the health of all learners and teachers is protected. At the same time, the learning process does not stop, because they received proper support.
The urgency of creating a national educational platform is due also the strategic need for sustainability and quality of education, as well as the need for equal access to knowledge for all learners in Ukraine, regardless of location and available resources”
Serhiy Shkarlet, Minister of Education and Science of Ukraine (2020–2023)
A platform tested by war
The full-scale invasion since 24 February 2022 fundamentally changed the platform’s role:
- During air raids, learners sheltering underground have kept up with lessons through VSO.
- In areas under temporary occupation, some students have downloaded material over mobile data at night, studied, then cleared it from their phones by morning — a routine repeated for months at a time.
- When missile strikes on the power grid have triggered rolling blackouts nationwide, the platform’s tolerance for weak or intermittent connections has kept lessons within reach.
Usage in 2026
In 2026 alone, 1,000,000+ people have used VSO — the highest figure recorded since the platform launched. Roughly 18% of them are outside Ukraine, in Germany, the United States, China, Singapore, Poland, Spain and elsewhere: families who left the country but kept their children enrolled in the Ukrainian state curriculum.
