Are You Dyslexic? Why Wait and Wonder? Let the Dyslexia Screening Test App from Neurolearning show you how you think and learn, and get you started on the road to a successful future. Our Dyslexia Screening Test quickly and accurately lets users ages 7 to 70 who have not previously received intensive dyslexia-appropriate reading instruction be screened for signs of the thinking and processing traits associated with dyslexia. The initial app download gives users access to the following free content: --The MIND-Strengths self-assessment surveys (for ages 7 and older), which allow users to discover their relative abilities in 4 key strengths areas associated with dyslexia --5 short videos describing what dyslexia is and is not, common signs of dyslexia, and what our screener can do for users --A brief pre-test to determine if you might be at risk for dyslexia --Comments by previous users on their experience with our app To take the dyslexia screener requires an in-app purchase of a testing slot. ---- The Neurolearning Dyslexia Screening Test App measures several key brain functions that underlie reading and spelling skills, and that work differently in individuals with dyslexia. It combines these measures with an assessment of current reading skills to determine the likelihood that the test user is experiencing challenges at school or work related to dyslexia. After the screening, users are provided with a detailed and individualized report of their results. This report includes: - A Total Dyslexia Score, which measures the overall likelihood that any problems they have with reading and spelling are related to dyslexia - Six Dyslexia Subscale Scores, which measure the key brain processing functions that underlying dyslexia-related challenges - Detailed and individualized recommendations outlining steps that can be taken to improve performance and limit challenges at school or work - A detailed list of resources that can be used to implement the recommendations - Recommendations on when further professional assessment is needed ---- Who should use the Neurolearning Dyslexia Screening App? Students 7 or older who: - Struggle to read, write, or spell - Have siblings or parents with dyslexia or other learning challenges - Read slowly or avoid reading - Underperform their apparent ability and “can’t show what they know” - Take longer to complete work or tests than expected - Struggle more each year as the workload intensifies - Received an unclear or confusing screening result at school Adults up to age 70 who: - Currently struggle with reading, writing, or speaking - Underperform at work for unclear reasons - Struggled in school but were never tested - Have never enjoyed reading, read slowly, or struggle when reading aloud - Have dyslexic children or grandchildren and recognize similar features in themselves ---- Neurolearning’s mission is to bring quality dyslexia testing within everyone's reach. For 20 years Drs. Brock and Fernette Eide have tested countless individuals with learning differences from all over the world in their Neurolearning Clinic in Seattle, Washington. They’ve also promoted better assessment and understanding of different learners through their influential books (“The Mislabeled Child” (2006) and the internationally best-selling book, "The Dyslexic Advantage" (2011)), and by the formation of the non-profit organization Dyslexic Advantage in 2012. The Eides are also frequent invited lecturers at conferences and meetings around the world, have been visiting lecturers at leading schools of education including Stanford University and Hunter College. In 2014 the Eides joined with pioneering technologist and entrepreneur Nils Lahr to found Neurolearning SPC, and to bring quality testing for learning differences within everyone’s reach.
