The bachelor thesis deals with the analysis of verbal subtests of selected Intelligence tests (Analytical Test of Intelligence, Kaufman Assessment Battery for Children, Vana Intelligence Test and Wechsler Intelligence Scale for Children). The analysis focuses on the types of verbal abilities and communication skills examined by those tests, and on types of exercises used in the psycho-diagnostics practice. The thesis concentrates on the tests used for diagnostics of verbal abilities in Czech children who are in the age group of up to 12 years. The theoretical part includes basic terms of the theory of Intelligence and Intellect abilities and basic knowledge of child development. The so called pre-school evolution is the most important period because of the child language acquisition and because of the development of communication abilities and skills at the lexical-semantic, morphological-syntactic, phonetic-phonologic and pragmatic levels. The thesis concentrates on the so called younger age evolution as this period is primarily connected with the school maturity / readiness.
