Rich, Flexible, and Built for Modern Assessment

Create Interactive, Engaging, and Meaningful Assessments
OASYS empowers you to design assessments that go far beyond simple questions — offering a wide and growing range of interactive formats to suit diverse testing and learning needs.

Versatile Choice Questions

Use single and multiple choice formats for quick checks, knowledge tests, and scalable assessments — with flexible layout and feedback options.

Choice Matrices

Collect structured, multi-dimensional responses — ideal for comparing items or evaluating multiple criteria in a single, compact interaction.

Open Text Fields

Allow free-form input for reflection, explanation, or detailed answers — ideal for capturing thoughts beyond predefined choices.

Inline Text Interactions

Add text gaps with drag-and-drop answers (with optional distractors) or fill-in-the-blank fields embedded directly into running text.

Sliders

Use interactive sliders to capture nuanced responses, from precise selections to intuitive ratings across a visual scale.

Rich Media Integration

Enhance your assessments with audio, video, and images — ideal for supporting multimodal content and engaging diverse learners.

Concept Maps

Let users create visual structures to express relationships, organize ideas, and demonstrate understanding beyond text-based answers.

Flexible Test Configuration

OASYS offers flexible test configurations, including templates, customizable navigation, a timer, and test availability settings. If a test is interrupted, it can be resumed later with the remaining time.

What’s next?

Upcoming features for 2025–2026 include new inline interactions, advanced drag-and-drop, file uploads, and graphical tasks — as OASYS evolves to offer even more interactive and accessible digital assessments.

OASYS lets you create fully customizable, interactive assessments — whether for education, training, research, or certification. With modern, user-centered features and a flexible structure, it adapts to a wide range of use cases and testing scenarios.

Designed in
Luxembourg

Originally developed for the national school monitoring program Épreuves Standardisées (ÉpStan), OASYS has been successfully used since 2010 in large-scale assessments, experimental studies, and survey-based data collection.

Today, it empowers teachers, test designers, and educational professionals everywhere to create and deliver digital assessments with ease.

Co-designed for Real Needs – Shaped by Real Users

OASYS is a flexible assessment platform designed to meet the diverse needs of educators, researchers, and professionals across sectors.
Still in active development and constant evolution, OASYS is being built in close collaboration with its users. Through co-design workshops with teachers, students, and other stakeholders, we define together what the platform should offer to simplify their workflows and support their goals.
By working hand in hand with current and future users, we ensure that OASYS remains a powerful, user-friendly, and adaptable digital tool — whether for teaching, training, research, or certification.
