Product Background

A new chapter in online language testing

Avant Assessment, developers of the first internationally recognized online language testing standard (STAMP), tapped into a massive demand for their services and quickly moved to expand the variety and capacity of their products. They earned the trust of educators, employers, and government agencies across the world, but unfortunately, their rapid growth outpaced their technological infrastructure.

Avant Assessment asked Twenty Ideas to restructure and redesign its fragmented network of products that was hard to manage and clunky to use. We modernized its product suite to allow this valuable evaluation platform to survive and thrive.


Realigned for the road ahead

Streamlining and updating Avant Assessment for safer, more agile future growth would both require structural and aesthetic improvements. On the backend, we would need to unify a broad suite of platforms and technologies to enable seamless software management for the client’s admin team. From a UX perspective, we would also need to make the digital assessments convenient, intuitive, and engaging for its primary users: language learners and teachers.

Bringing it all together

Our team analyzed Avant's eight different portal variations and identified the optimal infrastructure and interface to apply across its portfolio. Then, without disrupting service to its existing users (revenue base), we consolidated all Avant offerings onto one modern, cloud-based platform, applied consistent branding and design, and implemented processes for on-going project management.


Access made easy

We implemented a universal login that allows test takers and administrators to access all Avant products with the same user profile.

Breaking the sound barrier

Industry-leading integrated HTML5 voice recording technology replaced aging Flash plugins, reducing costs and bandwidth requirements to increase classroom accessibility.


Remodeled for modern users

Updated assessment interface presents questions and prompts in a clear, contemporary format to support comprehension and focus. It also features a custom-designed machine learning algorithm that can auto-score student writing responses.


Results you can see

New report designs for test takers and administrators break down scores and highlight specific areas for improvement, both for individuals and across test groups.

Evolution Unblocked

Consolidating Avant Assessment’s eight non-standardized products into one cloud-based platform cut hosting costs by 75%, while its modernized interface dramatically improved product adoption and engagement. These changes restored Avant Assessment’s power to evolve its platform, spurring immense growth for its team, revenue, and customer base.

Twenty Ideas brings a special combination of efficient management, elegant product design along with serious technology chops.
