The assessment takes around three hours and can be administered over either one or two sessions.

Following the assessment a full, detailed report is written and a feedback session arranged.


The fee is charged in three parts: a £75 deposit paid two weeks before the assessment, £210 when the assessment is completed and a further £155 is charged when the report is written. If dyslexia is not diagnosed or a report is not required the client has the option to decline the report and no further fee is due.


The assessment can be conducted at our offices in Orpington, Croydon, SE13 or occasionally at the client's home. Assessments conducted at a client's home incur an additional fee, depending on location.
