This paper describes the Tutor Assistant, an authoring tool for an Intelligent Language Tutoring systems (ILTS) for English as a Second Language (ESL). The common goal of authoring tools for ITSs is to reduce the costs in expertise and time that is required to produce a usable intelligent learning environment. The Tutor Assistant is designed to be usable by language instructions with little of no experience of ILTSs and ILTS authoring tools. This paper reports on a recent study which evaluates the degree to which typical users of our system can author good quality content for an ILTS and establishes benchmarks for development times.
