We present a uniform framework for dealing with errors in natural language sentences within the context of automated second language teaching. The idea is to use a feature grammar and to analyse errors as being sentences where features have other values than those they should have. By using a feature grammar it is possible to describe various types of errors (agreement, syntactic and semantic errors) in a uniform framework, to define in a clear and transparent way what an error is and - this is very important for our application - to analyse errors as arising form a misunderstanding or ignorance of grammatical rules on the part of students.
