Students must complete ISEF paperwork and submit copies of the appropriate forms (Forms 1, 1A, & 1B at the least) to the appropriate Science Fair Director before beginning their experiments. If the experiment requires extra paperwork, the project must be approved before starting. Instructions and rules may be found at Remember, you keep the original documents!
