During Spring 2010, Audrey Gutierrez and I designed and implemented an original assessment test, the “Parent Teacher Communication Diagnostic Test” (Component 9) to measure the constructs of reading, listening, writing, and speaking. In these contexts, an integration of the four language skills is necessary, which was the rationale behind the integrated skills test design featured in my MATESOL Portfolio. The experience of being immediately held accountable to our test takers made us question our work and carefully consider how assessment actually affects learners, positively and negatively. For instance, in order to complete the test, a learner must have some baseline literacy ability. As result of this project, I also discovered how to perform quantifiable analyses of test reliability and validity for this particular test in order to be a confident test administrator in the future.
