Most children over the age of 3 will enter kindergartens but are not compulsive.
After the child reaches the age of 6 (as defined on September 1st each year), he must enter the National Primary School (Volksschule) for a period of 4 Year of education. During the period, school-age children’s tuition, books, and school transportation expenses are borne by the state. In addition to the schools established in the general state, the schools that can be enrolled can go to local private schools under special conditions, and even study at home.
After the National Elementary School, schoolchildren are about 10 years old and can choose to enter ordinary or secondary schools for a period of four years. Ordinary secondary schools have entrance examinations that are required to pass the examinations; secondary schools do not have this restriction. If a school child has a special problem, he or she can choose a special school for his or her institution. After successfully completing the 8th grade (9 years of compulsory education), the students will face from four kinds of educational institutions, namely, ordinary high schools, high-level vocational training schools, intermediate vocational training schools, and multi-tech schools with advanced vocational schools. As soon as you study, each is a new stage, and only the high-level vocational schools require examinations and score thresholds. When you are promoted from a higher vocational school and an ordinary high school to higher education, you must pass the graduation test. 
The duration of study at an Austrian university is generally 4 to 5 years, of which the basic study period is 2 years and the professional study period is 2 ~3 years. Students must complete the required courses and elective courses within the prescribed number of years, obtain the necessary credits through the examination, write the graduation thesis in the final stage of the study, and graduate after passing. Austria only has an advanced degree in the university – a doctorate. Doctoral education is a natural continuation of undergraduate education. The doctoral students are not limited in age. There is no special institution for doctoral education. The main form is guided by the instructor. There is no bachelor’s degree in traditional studies, called Diplomstudium, which is divided into 2 to 3 stages (Abschnitt). The credits are awarded to the master’s degree after passing the graduation examinations and papers (Diplomarbeit) at various stages (Magister; engineering is Diplom-Ingenieur). After completing a master’s degree, you must enter the doctoral program (Doktoratstudium) and write a doctoral thesis (Dissertation). After the defense, you will be awarded a different doctoral degree according to the academic classification.
The Austrian academic system is rigorous. In principle, the doctoral field must be in the same category as the previous master’s degree. Austria has reformed higher education with a bachelor’s degree, but so far, only a handful of undergraduate programs have been offered, and most departments still teach under the traditional Diplomantudium practice. The Austrian public university adopts a divisional system, and the average level of each school is based on the hope that the subjects are subject to study and the convenience of transportation is the basis for school selection. In contrast to private institutions, public university diplomas are highly valued.
