Accurately identify Primary school children who would benefit from reading support, using our fast, fun and intuitive app for teachers and teaching assistants. Based on decades of University of Oxford research into reading development. ReadingScreen assessments consist of two tests measuring different reading skills. The first presents pupils with up to 60 individual words of increasing complexity. The second presents them with up to 34 nonwords. The pupil is asked to read each word or nonword out loud and their responses are marked for accuracy by the adult conducting the assessment. If they get 15 answers in a row incorrect, the test ends and they move onto the next test. Each assessment should take 10 minutes or less to complete. Assessments can be interrupted if necessary and will resume from the beginning of the most recent test. To launch an assessment, the adult conducting the assessment should scan the QR code for the pupil they want to assess. No personally identifiable information is stored on the device. At the end of an assessment, the data is uploaded to oxedandassessment.com for instant feedback and reports can be generated for classes or year groups. If no internet connection is available, the data can be stored on the device and uploaded at a later date. ReadingScreen is suitable for schools and organisations (UK and international) using English or Welsh as the medium of education.
