Persons seeking to meet the Iowa High School Equivalency Diploma requirements should be aware of companies that claim to offer the Test of General Educational Development (GED) over the Internet or through correspondence courses. There are NO online or correspondence testing programs recognized by the General Educational Development Testing Service (GEDTS) of the American Council of Education (ACE). Persons can ONLY take the Official GED Test Battery at an approved Iowa GED test center. The only way to receive an Iowa High School Equivalency Diploma is to successfully pass the Official GED Test Battery by Iowa state standards. The current Iowa state standard is to achieve a minimum standard score of 410 on each of the five Official GED Test Battery subtests and an overall standard score average of 450.
