Set up a table with your equivalences:

Excellent 5
Good 4
Average 3
Fair 2
Poor 1

In an adjacent column to your ratings, enter the formula:

(assumes ratings start in A1, and that the table is NAME'd tbl, although you
could use absolute cell references instead)


=VLOOKUP(A1,tbl,2,FALSE)

Average the resultant numbers.

If you do not want to use an adjacent column and lookup table, you could use
the following formula:

=SUM(COUNTIF(A:A,"excellent")*5,COUNTIF(A:A,"Good ")*4,
COUNTIF(A:A,"Average")*3,COUNTIF(A:A,"Fair")*2,
COUNTIF(A:A,"Poor"))/COUNTA(A:A)

You may want to adjust the reference to column A.

As Leo pointed out, I had the equivalences backwards, but you should be able to
change them easily.
