Sarah's background includes teaching English and assessing English and Spanish language skills. She has also written and spoken about corpus linguistics, writing evaluation, and spoken language assessment. Sarah has taught qualitative research for doctoral students and researched how multilingual families use augmentative alternative communication (AAC) devices with their children with disabilities. In addition, she is versed in quantitative analyses for language assessment, such as item response theory, Rasch measurement, and response process data (e.g., eye tracking).

Sarah was a postdoctoral research associate in Michigan State University's Early Language and Literacy Investigations Laboratory (ELLI Lab), conducting psychometric analyses on federally-funded grants to develop English and Spanish assessments for ages 3 to 7. She completed her Ph.D. in Applied Linguistics at Georgia State University, where she worked as the English Testing Coordinator and taught English as a second language (ESL) and linguistics courses. Sarah's dissertation topic, stemming from her experiences teaching oral communication, concerned examinees' control of audio play in ESL listening assessment. She has over 15 years' experience in research and development in language assessment, including five years with the University of Michigan English Language Institute Testing Division. Sarah has developed and scored test items for dual language learners of English and other languages, and for examinees with limited speech and/or language production.
