ETS challenged developers to create a math assessment task in the form of a game!

ETS is looking for developers and educators to create a game that acts as a math assessment. We’re looking for innovative ideas that produce evidence of students’ knowledge, skills, and abilities in mathematics. The assessment tasks should be based on a Learning Progression for some field of mathematics in K-12. We are providing two research-based Learning Progressions: (1) Variables and Equality (approximately Grades 5-9) and (2) Linear Functions (approximately Grades 7-10). You are invited to use either of these or supply your own for any other K-12 mathematical content.

$8,000 in prizes

Grand Prize

One Grand prize winner will receive $7,000 and an all-expenses paid trip for one person to showcase the winning project in a Learning and Games demo space at ETS in Princeton, NJ (estimated value: $1,000). The winner will also have the opportunity to discuss the ideas behind the entry with the Vice President of Research at ETS.

How to enter

  1. Create an account on or login with an existing ChallengePost account and read the complete challenge rules;
  2. Develop a working software application that runs on a widely available software platform (e.g. the web, desktop, iOS, Android, etc.). Applications may be final (ready for market or in market) or near final (in need of some additional levels or improved graphics, but fully functioning). Applications should be aimed at assessing student knowledge/understanding of one of the following topics, as described on the Learning Progression tab:
    • Variables and Equality (approximately Grades 5-9)
    • Linear Functions (approximately Grades 7-10)
    • Open Mathematics topic — must include a learning progression that has a basis in educational or psychological research (see the provided progressions for Variables and Equality and Linear Functions as examples). Any set of K-12 grade levels is welcomed;
  3. Create a brief written description of your application and a video describing how it distinguishes between levels of the Learning Progression (We have provided a framework that may be helpful to guide you in this thinking. Submitting the framework tables is welcomed but optional.) Upload the video to or; and
  4. Complete all required fields on the online Enter an Application form and upload a fully completed, signed Submission Agreement.

Judging Criteria

  • Reusability
    Judged on a scale of 1-5. 1: the ideas behind this task apply only in this specific game context; 5: the ideas behind this task can be applied to a wide range of game contexts and for a wide range of knowledge, skills, and abilities.
  • Measurement value
    Judged on a 1-5 scale. 1: data collected in the course of students’ game play does not target intended knowledge/understanding; 5: task perfectly targets evidence of intended knowledge, skills, and abilities.
  • Originality
    Judged on a scale of 1-5. 1: task is unoriginal; 5: task is innovative, unique, and creative.
  • Engagement
    Judged on a 1-5 scale. 1: task is boring/unengaging; 5: task is extremely engaging.
