Education
Bernard is within the Western Dubuque Community School District. Zoned schools include Cascade Elementary School, and Cascade Junior-Senior High School, both in Cascade. It was previously served by Bernard Elementary School, which was located next to the Bernard Commercial Club Park, on a plot of land. It opened in 1960, had its current building open in 1963, and received an addition in 1967. Family sizes in the area decreased, and as years passed the enrollment grew smaller and smaller. By 2017 the school was sharing employees with Cascade Elementary, and was required to send students in kindergarten and the second grade to Cascade Elementary as the numbers of students from those grades were too small; Bernard Elementary had a total of 31 students. The district stated that the yearly cost of operating the school per student was $14,000. In February 2017 four members of the school board voted to close the school while Mark Knuth, the president of the school board, chose to abstain from voting. Students were reassigned to Cascade Elementary.
