That's according to the Minister for Education.
More than 50 primary schools in the midlands have three or less teachers employed.
That's according to the Minister for Education, Norma Foley, who released the figures in a response parliamentary question.
20 schools in Westmeath have a Principal and one or two mainstream classroom teachers - that's followed closely by a figure of 19 in Laois, and 15 in Offaly.
Across the country, over 500 primary schools had a Principal and just one mainstream teacher employed.
However, Minister Foley says there's been an improvement in the pupil to teacher ratio, which was 15.7 to one in 2017 - that number was 13.4 to one last year.
