You know code. Scientists know data. Help NIST improve the way we share our scientific reference data by building an App today!

Scientists and engineers need data—from the atomic weight of carbon and the structure of benzene, to the most precise value for the speed of light. High quality physical and chemical reference data help researchers design experiments, build better products, solve health and environmental problems, and even study the stars. The National Institute of Standards and Technology, NIST, is a non-regulatory agency of the United States Department of Commerce. NIST provides some of the most accurate and comprehensive datasets in the world. Physicists, biochemical engineers, environmental researchers, and many other technically trained experts routinely use NIST Standard Reference Data in their workday. Students from high school through graduate school use the same datasets to master the ropes of scientific discovery. Help drive innovation and support research by developing your own mobile applications that use NIST Standard Reference Data!

See Rules for Full Details 


Eligible participants are invited to submit an App that uses at least one of the Eligible NIST Datasets

A submission requires:

(1) your App (see minimum App criteria) provided to NIST at no cost; 

(2) a brief (fewer than 250 words) text description of your App;

(3) at least one screenshot image of your App in use on a mobile phone or tablet device;

(4) a brief (less than five minutes) video demonstrating the functionality of your App; and

(5) confirmation that you have read and agree to the Competition Rules contained in this Notice.

How to enter

  1. To enter, create a user account at ChallengePost by visiting and register your interest in participating in the Competition at the Event Website,
  2. Make sure you are eligible to be a Participant in this Competition, and that you have read the Rules.

Judging Criteria

  • Potential Impact
    How strong is the potential of the submission to help students and other technical experts use NIST Standard Reference Data?
  • Creativity and Innovation
    To what degree is this submission innovative? Does it bring new thinking and creativity to improving access to NIST Standard Reference Data?
  • Implementation
    Does the App provide an engaging user experience and have interactive capabilities? Does it work well? Make sure your App meets the minimum criteria described in the Rules!
  • Uses Scientific Reference Data
    Does the App use at least one of the Eligible NIST Datasets? Preference will be given to applications that integrate more than one dataset.
