About the Okayama Public High School Entrance Examination — Science Exam
The Okayama Prefectural High School Entrance Examination in Science (岡山県公立高等学校入学者選抜学力検査 理科) tests lower-secondary graduates on physics, chemistry, biology and earth science, aligned to the MEXT 平成29年 (2017) Course of Study for junior-high science. The 令和8年度 (2026) selection has two main routes: 特別入学者選抜 (出願 1月20-22日; 学力検査 2月4日, 国・数・英 45min/70点, 英語聞き取り; 面接・選択 2月5日; 結果通知 2月13日) and 一般入学者選抜 (出願 2月24-26日; 学力検査 3月10日, 5 subjects 社→数→国→英→理; 面接・実技 3月11日; 合格発表 3月18日). 倉敷天城(理数)・津山(理数)・玉野光南(体育)・井原(地域生活) admit 100% via 特別入学者選抜. 普通科学区 has 6 zones (岡山・倉敷・美作・西備・備北・東備) plus 13 schools accepting from the whole prefecture. Selection uses the 段階相関方式 with 学力 350 + 調査書 200. The R8 average for 理科 was 62.1 (100点換算, 5,586 candidates). The official R8 教科分析 notes that overall non-response was low, but candidates struggled especially with エネルギー分野 実験・観察の考察 items and with items linking actual phenomena to concepts through 図示・説明.
Assessment
45-minute paper worth 70 points, aligned to the MEXT 中学校学習指導要領 理科編, covering physics, chemistry, biology and earth science, with 実験・観察 result interpretation and 記述 (constructed-response) items including 観察・実験の考察 and 図示・説明. The five academic-test subjects (国語, 社会, 数学, 理科, 英語) are each 45 min/70 points, so the five-subject total is 350 points. The 理科 paper is sat last on 10 March 2026 (order 社→数→国→英→理). 岡山朝日高校 uses self-made problems for 国語・数学・英語 only; 理科 uses the common paper for all schools.
Time Limit
45 minutes (the 一般入学者選抜 academic test 学力検査 is sat on 10 March 2026, science last of the five; results announced 18 March 2026)
Passing Score
No fixed prefecture-wide pass mark. Admission is decided by each school using the 段階相関方式, which combines the academic test (学力検査, 350 points from five subjects each worth 70) with the report card (調査書, 200 points = 中1 45 + 中2 45 + 中3 110). The first selection (第1選抜) fills about 90% of places from first-choice applicants; the second selection (第2選抜) fills about 10% from second-choice applicants. Per-school selection may also apply 傾斜配点, weighting a designated subject more heavily. There is no single prefecture-wide pass line.
Exam Fee
¥2,200 入学選抜手数料 (entrance selection fee), the figure published by Okayama Prefecture for its prefectural high schools; the same ¥2,200 applies to both the 全日制 (full-time) and 定時制 (part-time) courses. On admission a separate 入学金 of ¥5,650 is payable. The fee covers the whole 学力検査, not an individual subject paper.

Okayama Public High School Entrance Examination — Science Study Tips from Top Performers
Frequently Asked Questions
Is this question bank the same as the real Okayama science paper?
No. The official paper is written in Japanese with 観察・実験の考察 and 図示・説明 constructed-response items that multiple-choice questions cannot reproduce. This bank is an English-language multiple-choice study adaptation of the same syllabus content and cannot replace experimental or practical science learning.
How long is the Okayama science paper and what is it worth?
It lasts 45 minutes and is scored out of 70 points. The five academic-test subjects (国語, 社会, 数学, 理科, 英語) are each 45 min/70 points, so the five-subject total is 350 points. 岡山朝日高校 uses self-made problems for 国語・数学・英語 only; 理科 uses the common paper for all schools. Per-school selection may apply 傾斜配点, weighting a designated subject more heavily.
How is admission decided in the Okayama selection?
Admission uses the 段階相関方式, combining the academic test (学力検査, 350 points) with the report card (調査書, 200 points = 中1 45 + 中2 45 + 中3 110). The first selection (第1選抜) fills about 90% of places from first-choice applicants; the second selection (第2選抜) fills about 10% from second-choice applicants. Each school decides per its own criteria, and there is no single prefecture-wide pass line.
How much is the examination fee?
The 入学選抜手数料 (entrance selection fee) for an Okayama prefectural high school is ¥2,200, the same for the 全日制 and 定時制 courses. It is paid once for the whole five-subject 学力検査, not per subject paper. Students who are admitted then pay a separate 入学金 of ¥5,650. Okayama Prefecture publishes both figures on its 県立学校の授業料等 page.
When were the 2026 papers sat and results announced?
In the 令和8年度 (2026) 一般入学者選抜, the academic test (学力検査) was sat on 10 March 2026, with the 理科 paper last (order 社→数→国→英→理). 合格発表 was on 18 March 2026. The 特別入学者選抜 academic test was on 4 February 2026, with 結果通知 on 13 February 2026.
Which content areas are covered on the Okayama science paper?
The paper covers the four MEXT junior-high science fields: physics (運動と力, 電流, 光と音), chemistry (物質の状態, 化学変化と質量保存, 原子・イオン, 水溶液・溶解度), biology (細胞, 植物, 動物の血液循環, 刺激と反応, 生態系・遺伝), and earth science (地球の構造, 天体, 気象, 地層・化石). The official R8 analysis notes that candidates found energy-domain experiment reasoning and phenomenon-to-concept diagram items hardest.
