Twice-exceptional learners have both high ability and learning difficulites. Sometimes their abilities mask their difficulties, and sometimes their abilities are hidden by their difficulties. These students may struggle in school - and express frustrations at home - when their needs are not met.
Learning difficulties may arise from specific learning disabilities, for example, dyslexia, dysgraphia, and discalculia. Difficulties may also be a result of attention issues. You can find more information on Learning Disabilities and Attention Deficit Disorders at the Learning Disabilities Association of Ontario website.
High-ability learners with autism may also experience difficulty learning. You can find more information on Austism Spectrum Disorder at the Autism Ontario website.
Some high-ability learners expereince social, emotional, or behavioural issues that interfere with their learning. The SENG website has lots of information about supporting the social and emotional needs of high-ability learners.
The Gifted and Learning Disabled Handbook, by Canadian educators Corinne Bees (2009) provides an excellent guide for parents, eductors, and all supporters of 2e students.
