CHEAR Moving Forward

NIEHS funded the CHEAR program from 2015-2019 to provide NIH researchers access to laboratory and statistical analysis services for adding exposure assessment to their studies of children’s health. Moving forward, the CHEAR program has been replaced by HHEAR.

  • New requests for CHEAR services are no longer being accepted.
  • Researchers can search CHEAR studies and download public de-identified datasets through the CHEAR Data Center.
  • Researchers with active CHEAR projects can continue to access their myCHEAR account to track the progress of their projects
