Some state boards ask that the PE provide one PDF file containing all certificates of completion. This can be easily done using most PDF manipulation software including Adobe Reader. But, be advised that some programs that combine multiple files can cause certain information on the resulting file to be illegible, scrambled, or missing. This generally happens when the software you are using is older and does not comply to the newest standards for PDF production. Make certain to closely compare the final file to the original and be sure that all information appears as it should before submission to the board.
