how can I scan a certificate and save it for editing purposes?

If you scan something from paper to the flatbed or document feeder scanner, you will have no purpose with Acrobat. Acrobat will edit text from a PDF where the source was Word or similar. Anything scanned from paper through an imaging scanner, will have to be edited on pixel level (Adobe Photoshop or similar). It means if you've never done it, you'll need a crash course in image editing.

Thank you everyone for answering my question.  I tend to easily forget that the scanned document will have to be converted to a file format, like .doc, .txt, etc. before it can be edited using Microsoft Word.  Seeing that it is text that I am needed to edit, MS Word should do the trick.

Thanks for the points, @GMartin, but please let us know what method you will be using to go from the scan to the corrected certificate.

Hi Everyone,

             The certificate was scanned using the integrated software tools which came with my HP ENVY Photo 6255 and saved as a PDF file.  Now, an important consideration here is that the file can only be viewed, but, not edited.  To get it to the point of being edited, I opened it with Adobe Acrobat XI Professional,  saved it as a editable document by converting the PDF file to a Word document, and closed it.  Then, I opened MS Word 2013 and began the editing the new file saved as a document within Adobe Acrobat XI Professional.  One more point which merits bringing up is the fact that there is usually some additional editing required because the conversion has a tendency of altering the original formatting of the document.  I have not found a way of making the conversion to be 100% error free.    I am not really sure if there is a way either at the present time.

Original formatting will ALWAYS need to be fixed manually, no matter what product you use. There maybe some percentage points increase in quality by switching to other (mostly paid) products, but it won't be much. As you may have noticed, the feeder may introduce a slight skew to the scan, increasing layout differences. To avoid it, you can line up the corners of the paper to be scanned on the scanning glass' corner. Very unproductive, but you need to test if manually scanning one by one (and making sure you align the corners), may still increase work flow efficiency IF the resulting scan may need LESS manual editing.
Yes, the perfect digital copy still isn't in the near future. No perfect handwriting recognition, Nor is there perfect speech recognition. Anything digitized is basically still in its infancy
