GREATER PERSISTENCE IN TEACHING WAS FOUND AMONG MEN RATHER THAN WOMEN, OLDER RATHER THAN YOUNGER PERSONS, UNMARRIED RATHER THAN MARRIED WOMEN, SECONDARY SCHOOL RATHER THAN ELEMENTARY SCHOOL TEACHERS, THOSE MORE SATISFIED WITH THEIR TEACHING EXPERIENCES, AND AMONG WOMEN WHOSE HUSBANDS EARN LESS THAN $10,000 A YEAR.
