The Instruction Manual for Braille Transcribing, Chapter 19 discusses what is necessary for your trial manuscript. The information I quoted in my previous post was taken from the Instruction Manual, which refers to Braille Formats and the rule for preliminary pages. Remember, you only braille what you want to include in your trial manuscript. If you do not want to do the acknowledgment (as it is not listed in the requiremnts for your trial manuscript, then do not include them. If they are part of the text information, you will need to follow the rule that applies to your instance.
