The modern system of special education in the Republic of Kazakhstan is undergoing significant
changes. Following the global practice of ensuring equal access to education, schools for hearing
impaired children are switching to updated curricula, the topics and requirements of which are
equivalent to those of ordinary schools. The successful learning of deaf and hearing-impaired children
requires qualitative changes in the forms and methods of pedagogical influence on students.
However, to evaluate the effectiveness of the learning process by traditional methods in this case is
difficult, since it is necessary to implement a correction component in the new environment. This
article shows the concept of learning effectiveness within a school for hearing-impaired children. It
identifies a number of qualitative indicators that affect the learning process of children with special
educational needs, including the need to use modern information technologies. The paper proposes
a developed mathematical model for evaluating pedagogical efficiency in a special school, describes
the technology of its application and testing results to confirm the functionality.
