1. Diagnostic: conducted by a psychologist of the Center for Special Developmental Pediatrics (tasks in a game form for the child) and includes a questionnaire for parents/guardians (filled out by parents online after the child's diagnosis is completed). The results of the questionnaire are automatically included by the system in the general diagnostic algorithm.
2. Analytical: calculation of results by a psychologist (fixing scores occurs during and after the diagnostic part) and preparation of a report based on the results.

PEP-3 makes it possible to determine the level of skill development and provides information for making a diagnosis and determining the severity of the deviation. This is a standardized, age-appropriate scale designed to assess the development of motor and communication skills, as well as the presence of maladaptive behaviors in children with ASD or other pervasive developmental disorders (PDD), as well as in cases of suspicion of the presence of these conditions.

PEP-3 was developed to help teachers determine the child’s belonging to the diagnostic group (ADD or other PDD), as well as in the development of an educational program for him.

The total duration of the diagnosis is 120 minutes (2 consultative meetings of 60 minutes each). It is possible to hold 2 meetings on different days.

If necessary (subject to the subjective condition of the child), additional meetings may be scheduled to complete the diagnosis, which are paid for separately.

The diagnosis is prescribed after consultation with a neurologist, special psychologist, speech therapist, and pediatrician.

The diagnosis is performed on children aged 2 to 7.5 years.
