A study investigated the extent to which all-Irish primary schools in the Dublin (Ireland) area: (1) provide opportunities for parents not using Irish at home to send children to an all-Irish school; (2) provide impetus for an increase in Irish use in homes of attending children; (3) increase interaction among Irish-speaking families; (4) are related, by their location, to the distribution of Irish-speakers in the Dublin area; (5) build the level of Irish-speakers in the communities they serve; (6) encourage parents who value all-Irish education to move to an area served by an all-Irish school; and (7) are systematically related to all-Irish preschool and secondary education through the language. The report describes some general characteristics of the all-Irish elementary schools, then summarizes and discusses findings on the reasons given for sending children to them, home use of Irish, and use of Irish outside the home. Some data tables, the survey questionnaire, and maps of all-Irish school family distribution are appended. (MSE)
