DDE-2

DDE-2 is a standardised psychological instrument used to identify dyslexia (reading difficulties) and dysorthographia (writing difficulties) in children aged 7 to 15.

It is used by psychologists, speech therapists, and education specialists to differentiate between common developmental delays in school skills and specific learning disorders.

The assessment targets two essential domains: reading and writing. In reading tasks, speed and accuracy for words and non-words are analysed, offering relevant information about how the child decodes written text.

For writing, the test includes dictation exercises that highlight mastery of spelling rules and the types of frequent errors.

An important advantage of DDE-2 is that results are reported against standardised norms, allowing objective evaluation according to the child’s age. This helps specialists determine whether the identified difficulties fall within dyslexia and/or dysorthographia.

Based on the obtained profile, the test supports an individualised intervention plan, which may include exercises for reading fluency, improved spelling accuracy, and effective learning strategies.

In conclusion, DDE-2 is not only an assessment tool, but also an essential support for targeted interventions that contribute to school progress and the development of core academic skills.
