In Eastern Europe WT was against higher education as far I remember. There were handful college educated people in my KH, but majority of the JWs are barely literate there, usually having only mandatory education to the age 16. During communist rule, many JWs were denied higher education by the government and were forced to work in the coal mining areas. This education deficit caused by repressive government is very visible in the group born before 1968.
Other refused to got to professional schools because they were discouraged by the elder. I had numerous talks about my higher education with my elders and I got my undergrad and postgrad after WT world. All my JW relatives have basic education. My mom got her education before she got involved with the cult. Various studies in Czech Republic and Slovakia had often put JWs as one the least literate demographic group out there, just bit better than gypsies. The Czech census from 2011 indicates that less than 7% of JWs have college education, while 13.5% of Catholics, 42% of Jews, 16% of 7DA, and 20% of Czech protestants.
