The requirements for certification have been standardized for all NASA Centers in the past two years and now require that a trained content expert present hands-on activities and security training using the Sample Education Disks. The workshop is a minimum of 3 hours for Lunar or Meteorite certification and 4-6 hours for both Lunar and Meteorite Certification combined.
The certification workshop is free of charge and conducted through the Aerospace Education Services Program. The Aerospace Education Services Program specialists are trained content experts and you can schedule a workshop from them by completing and submitting the request form. They will get back to you with a schedule.
A certification workshop might also be offered in a seminar in your area. As mentioned the workshop is free; however, there could be a charge for certain seminars. Please check with your local NASA Field Centers for those dates and times.
