- Polish care path: the regulation of the Ministry of Health (MZ) on guaranteed services in primary care (POZ) (consolidated text, the Journal of Laws, Dz.U. 2023 item 1427, annex 1 part III, item 5) provides, as part of the health checkup at 2 years of age, for a test of the development of hearing responses and an assessment of speech development. This is the timing of the checkup and what is assessed then, not an age range for skills.
