Learn English – To capitalize “department” or not

Principal should be capitalized when used as a title preceding the name of the person but uncapitalized if used as a description following the name. For example,

Let us welcome Principal Bob.

Let us welcome Bob, the principal of the school.

See for example Blue Book of Grammar and Punctuation.

Whether it's a title or not, these two sentences are invariant:

1. Come to this class so you can become a super helper.

2. We have twenty-seven super helpers.

To see this, if you decide it is a title, replace "super helper" with "doctor" and the correct capitalization will be clear. If it's not a title, while you might capitalize the "Super Helper program" as it's a name, you would not capitalize the product of the program, i.e. the "super helpers."

It does not seem like "super helper" would be an official title or honorific at your company as it's pretty condescending (perhaps the actual program sounds better). If it is functioning as a person's title, the only instance it is capitalized is directly preceding their name, as in "Give your report to Super Helper John." Note that some titles are exceptional; you should "Bow before the King," but "Submit your work to the professor."
