Additionally, while secondary education often faces a dramatic drop in females because of the financial burden, Tanzania has reached gender parity in enrollment. One-third of girls are still married by age 18, and most of them come from poorer families. As mentioned before, English is the official language of secondary school, both private and public, which leads to challenges for the majority of students that come from Kiswahili focused primary schools. In 2009, only 35.4% of students passed the English portion of the National Standard 7 Exam, but this does not affect their ability to go to secondary schools. English in secondary schools is extremely controversial because while some people believe that students will become prepared to understand the global economy, many others believe that the focus on other subjects drops because a significant portion of time goes into learning English. If communication is not possible and questions are difficult to ask, it is difficult to retain information and critically think. The core and compulsory subjects in Forms 1 and 2 that are offered by all schools include Mathematics, English, Physics, Chemistry, Kiswahili, Biology, History, Geography, Civics and Religion. The optional subjects in Forms 1 and 2 include Home Economics, Information and Computer Studies, additional Mathematics, Music, Fine Arts, foreign languages, Islamic studies, Bible knowledge, and physical education. Students may choose none or any one or two of the listed subjects if offered at their school. The core subjects in Form 3 and 4 offered by all schools include Mathematics, English, Kiswahili, Biology, Civics, Religion, History, Geography, Physics, and Chemistry. The optional subjects in Form 3 and 4 include Home Economics, Information and Computer Studies, additional Mathematics, Music, Fine Arts, French, Arabic, Islamic Studies, Bible knowledge, and physical education. Tanzania reemphasized the value of sports like soccer in 2009, and in addition to that, debate and religious groups are popular after school activities. Parents and teachers have slowly began to value these activities in the development and growth of students. A national standardized exam is given at the end of Form 2, although there is no consequence for failing it. Another national standardized exam, the Certificate of Secondary Education Examination, is given at the end of Form 4. A student who passes is given a school-leaving certificate by his or her school. The student is also given an academic certificate by the National Examination Council of Tanzania. This certificate indicates the student's level of performance in several subjects, with division I being the best performance and division IV being the worst.
