I'd guess these terms are used fpr grading purposes as done in school. In Germany a 4 (ausreichend) is the quivalent of a "D" in American high schools, a "3" (befriedigend)is the equivalent of a "C".
This most common German grading system ranges from 1 to 6.

(I am a German high school teacher.)

Using the words in a text, I think "satisfactory" is used when it refers to a person, whereas "sufficient" is more refering to things.
Then there is of course the German school grades, "ausreichend" being equivalent to "D", "befriedigend" meaning "C".

would 'pass' work for ausreichend?

for "ausreichend" you would go for "passed"

ok thx!

@Can you provide a specific context?

This is a German school report.

Use adequate and satisfactory, as in the other recent thread ;-)
