Dyscalculia primarily affects the learning process in relation to Mathematics. Two of the types of dyscalculia that have been identified are:

• Type 1: developmental dyscalculia where students exhibit a marked discrepancy between their developmental level and general cognitive ability as it pertains to Mathematics. As a basic indicator of developmental dyscalculia students will perform below expectations with no obvious explanation (e.g. general ability, emotional state or illness) available.
• Type 2: dyscalculia where students exhibit a complete inability to manage mathematical concepts and numbers. It presents as an enduring condition that affects the ability to acquire mathematical skills despite appropriate teaching.
