5. What are the relevant contents of the "Implementation Measures for the Academic Level Examination of Ordinary Senior High Schools in Liaoning Province"? The Provincial Department of Education issued the "Implementation Measures for the Academic Level Examination of Ordinary High Schools in Liaoning Province", which was implemented by the first-year students of ordinary high schools who entered the school in the fall of 20 18.

Ordinary senior high school academic level examination is divided into two categories: qualified examination and graded examination, and the examination results are an important basis for students to graduate and further their studies. Students registered in ordinary high schools should take the qualification examination. Students apply for the exam for the first time in senior two, and each candidate applies for each subject once. If the result is unqualified, you can make up the exam again.

If you take the college entrance examination, you have to take the grade exam in senior three. High school students can choose 3 subjects from 6 subjects in the graded examination according to their interests, specialties and requirements of colleges and universities. The examination time is March every year, and students are provided with an examination opportunity for each subject temporarily, which is only valid for college enrollment in that year.

The new "3+3" test method will be adopted for the college entrance examination for senior one students enrolled in the fall of 20 18, that is, Chinese, mathematics, foreign languages and academic proficiency tests will be used as the college entrance examination results. According to the plan of the Ministry of Education, the "two basics" of the future college entrance examination refers to the unified college entrance examination results and high school academic level examination results, and the "one reference" refers to the comprehensive quality evaluation of students.

The "6 out of 3" subject exam is tentative. Students in ordinary high schools can only take 1. According to their own interests, specialties and the requirements of colleges and universities, registered students in ordinary high schools can independently choose three subjects from the six subjects in the graded examination, and the scores of the selected subjects should meet the standards. Other senior high school students and social workers who meet the requirements of the college entrance examination need to take the grading examination with senior three students in ordinary senior high schools.

Each subject of the graded examination temporarily provides 1 examination opportunities for students at school. Students registered in ordinary high schools should take the qualification examination. If they take the college entrance examination, they should also take the grade examination of senior three.

Each candidate 1 test. If the result is unqualified, you can only retake the subject 1 time. Candidates who fail the 10 subject qualification examination organized by the whole province can choose to make up the exam in July next year or in February of 65438+ (senior three students can only make up the exam in February of that year).

Students who fail in general technology, physical education and health, music and art, physics, chemistry, biological experiment operation and foreign language listening and speaking in the qualification examination will be organized by the municipalities to make-up exams. Make-up time shall be arranged by the municipalities within the third year of senior high school, but not later than the middle of April of the next semester of senior high school.

Registered high school candidates who have not completed the compulsory content study are not allowed to apply for the qualification examination of this subject. After dropping out of school, the original test scores of "degraded" students will be invalid. Grading examination subjects are determined by the office of the Provincial Admissions Examination Committee, which can be queried online.

Students transferred from other provinces and cities have invalid grades in other provinces and need to take the exam again in our province. When students transfer to other provinces, the office of the Provincial Admissions Examination Committee will issue a certificate of academic level examination results for them.

Students who return to the next grade after dropping out of school will have invalid test scores in the original grade and need to take the test again. The scores of qualified examination subjects are determined by the Provincial Department of Education and can be queried online.

Students who are transferred from other provinces and cities (or municipalities directly under the Central Government and autonomous regions, the same below) to ordinary high schools in our province (they must obtain the status of ordinary high schools in our province, the same below) and have participated in the ordinary high school qualification examination organized by examination institutions in other provinces and cities may apply for the qualification examination results certification of the corresponding subjects in the provincial high school proficiency examination. Our office entrusts the office of the Provincial Admissions Examination Committee to carry out the certification of transfer students from other provinces and cities and issue the certificate of academic level of ordinary high schools in Liaoning Province and other related work.

The results are only included in the total scores of the three subjects selected by the students who are valid for one year in that year, and the results are only valid for the enrollment of ordinary colleges and universities in that year. Students who transfer to grade 20 18 due to reasons such as suspension from school are valid for 1 year, but they cannot be used as grade examination results.

Passing the exam is the main basis for ordinary senior high school students to graduate and identify high school equivalent. The scores of students' academic proficiency test are provided to the enrollment colleges, and also used by the education administrative department to strengthen curriculum and teaching management, teaching quality monitoring and teaching feedback and guidance.

Ordinary high school students' qualification examination, examination subjects' scores, and credits' academic scores all meet the graduation requirements, and the graduation certificate of ordinary high school in Liaoning Province is issued by the Provincial Department of Education. Those who fail to complete the credits or 1 subjects and above in the qualification examination will be awarded the equivalent certificate of ordinary high schools in Liaoning Province by the Provincial Department of Education.

Ordinary high school students who have been approved to implement integrated courses in Chinese-foreign cooperatively-run schools (projects) in the province meet the relevant provisions of the education department and meet the graduation requirements. The Education Department will issue the graduation certificate of ordinary high schools in Liaoning Province with the words "international courses". In senior high school, students from other schools and relevant social personnel take the qualification examination of Chinese and other subjects 10 organized by the province, and the results meet the qualification requirements, which can be regarded as having the same academic ability as ordinary senior high schools. The Provincial Department of Education will issue the equivalent certificate of ordinary high schools in Liaoning Province.

A Examination subject qualification examination includes Chinese (including national language and Chinese), mathematics, foreign languages (including English, Japanese and Russian), ideological and political, history, geography, physics, chemistry, biology, information technology, general technology, sports and health, music, fine arts, etc. 14 subjects.
