In this paper we address the need for replication studies in the field ofsecond language acquisition and discuss the problems surrounding standards of reportingresearch. A particular focus is on the level of detail necessary for replication to take place. Thelack of uniform standards is noted with specific examples of problematic reporting taken fromdescriptions of second language learners' proficiency levels and measures of linguisticaccuracy in second language writing research. We propose ways that we believe will lead tomore thorough reporting of research and that will therefore allow others to engage inreplication.
