Avant Assessment

Taking-on platform sprawl to keep an industry leader on top

We helped Avant Assessment strengthen its language testing products from both the bottom up and the top down.


Online language testing leader Avant had grown its platform offerings quickly, but not strategically

Its fragmented network of products had become hard to manage and clunky to use

Infrastructure inconsistencies and tech debt were blocking further expansion and evolution


Consolidated eight non-standardized products into one cloud-based platform

Hosting costs cut by 75%

Modernized interface dramatically improved product adoption and engagement, spurring immense growth for its team, revenue, and customer base


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.

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.

Reassessing the user experience

New tools and reporting configurations provide greater control and clearer feedback to users on both sides of the testing experience.

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.
