Apologies for cross-posting. I am seeking TVIs to complete an online research survey. You are eligible to participate if * You are a certified or licensed TVI in the United States, and * You have worked as a TVI in the past 18 months. The survey takes approximately 10-15 minutes to complete. The purpose of the survey is to better understand what TVIs know about language and linguistic concepts related to reading instruction. It consists of 70 items in total, including: * 12 demographic/background questions * 2 questions about your perceptions of your teaching ability * 38 questions about language concepts * 16 questions about dyslexia * 2 open-ended questions Data is collected anonymously, so there will be no way to connect your responses back to you. The study has been approved by the Institutional Review Board of Northern Illinois University. Click on the link below to take the survey, and please forward it to anyone you know who is a TVI in the U.S. https://niu.az1.qualtrics.com/jfe/form/SV_bwJhcpMNiPNQV3T To meet security requirements of the university ethics board, the survey was developed in Qualtrics, which is not fully accessible to people with visual impairments. Contact me directly at lharris3@niu.edu for a fully accessible version of the survey. Thanks for your time, and feel free to contact me at lharris3@niu.edu<mailto:lharris3@niu.edu> if you have any questions. Lindsay N.
