Explore the sound and letter-pattern skills used in reading with the Online Reading Tutor (ORT) screener. A parent or legal guardian can guide a child through the activities, and adults can screen themselves. In about 5 to 10 minutes, listen to sounds, choose matching letter patterns and view a summary of reading accuracy. ORT's approach focuses on decoding: connecting letters and letter patterns with their sounds. Its separate reading program uses Orton-Gillingham-based activities to practise these skills, with the goal of making decoding more automatic so readers can give more attention to understanding what they read. This app provides the screener; it does not include the reading program. Before screening, the app presents a data collection notice and asks for permission to process the answers and results. Before results are shown, it requires contact details and asks you to choose how ORT may follow up. You can choose email without a call. A follow-up may explain the results and discuss ORT's separate reading program. Read ORT's Privacy Policy at https://onlinereadingtutor.com/privacy-policy/ and Terms of Use at https://onlinereadingtutor.com/terms-of-use/ for information about the service, data use and your choices. This app is not a medical device and does not diagnose, treat, cure or prevent any medical condition. The results are screening information, not a diagnosis of dyslexia or another learning condition. Consult a qualified healthcare professional for medical advice, diagnosis or treatment.
