1級施工管理技士は、第一次検定（学科）の合格率が4割前後、第二次検定（実地）の合格率が5～6割程度で推移し、全体としては「難易度が高い」とされていますが、特に第二次検定の記述式問題（経験記述）が難関で、実務経験を論理的に記述する力が求められるため、専門知識と文章力が必要。受験者のレベルが高く、特に建築・土木系では総合合格率が10～20%程度になることもあり、通信講座や添削指導の活用が推奨されます。
1級施工管理技士 難易度のポイント
- 第一次検定（学科）: 知識の広さと深さが問われ、合格率は40%前後。過去問対策で独学も可能だが、油断は禁物。
- 第二次検定（実地）:
- 経験記述: 実務経験をテーマに沿って論述する形式で、これが最大の難関。添削指導なしでの独学は難しい。
- 受験者層: 実務経験者のみが受験するため、受験者のレベルが高く、合格率が50〜70%台でも「簡単」ではない。
- 総合難易度: 最終的な合格率は、第一次・第二次を合わせて10～20%程度と非常に低い年もあり、専門的な対策と計画的な学習が必須。
資格ごとの傾向（例）
- 1級建築施工管理技士: 第一次検定は4割前後、第二次検定は5割前後（令和3～6年平均）で、最終合格率は低め。
- 1級電気工事施工管理技士: 第一次検定は4割前後、第二次検定は5～7割程度で、やや難しいレベル。
- 1級管工事施工管理技士: 第一次検定は3～4割台、第二次検定は約6～7割台で推移。
対策のポイント
- 第一次検定: 過去問中心の学習で基礎知識を固める。
- 第二次検定: 自分の実務経験を整理し、プロの添削を受ける（通信講座・講習会利用が有効）。
結論
1級施工管理技士は、受験資格（実務経験）のハードルと、専門知識・論述力が求められる試験内容から、決して易しい資格ではありません。特に、自分の経験を試験に活かす「経験記述」対策が合格の鍵となります。
The pass rate for the First-Class Construction Management Engineer Examination (theoretical) is around 40%, and the pass rate for the Second-Class Construction Management Engineer Examination (practical) is around 50-60%, making it generally considered “difficult.” However, the second-class exam’s written questions (experience descriptions) are particularly challenging, requiring the ability to logically describe one’s work experience, necessitating specialized knowledge and writing skills. The level of test takers is high, particularly in architecture and civil engineering, where the overall pass rate can be around 10-20%, so taking advantage of correspondence courses and textbook editing is recommended.
Key Points of Difficulty for the First-Class Construction Management Engineer Examination
First-Class Construction Management Engineer Examination (theoretical): The breadth and depth of knowledge is tested, with a pass rate of around 40%. While self-study is possible by studying past exam questions, caution is advised.
Second-Class Construction Management Engineer Examination (practical):
Experience Description: This exam requires candidates to write an essay about their work experience based on a specific topic, making it the most challenging part of the exam. Self-study without textbook editing is difficult.
Candidate demographic: Only those with work experience are eligible to take the exam, so the test is highly skilled. Even though the pass rate is in the 50-70% range, it is not “easy.”
Overall difficulty: The final pass rate for both the first and second exams is sometimes as low as 10-20%, so specialized preparation and planned study are essential.
Trends by qualification (examples)
1st-class architectural construction management engineer: The pass rate for the first exam is around 40%, and for the second exam it is around 50% (average from 2021 to 2024), making the final pass rate low.
1st-class electrical construction management engineer: The pass rate for the first exam is around 40%, and for the second exam it is around 50-70%, making it a somewhat difficult level.
1st-class plumbing construction management engineer: The pass rate for the first exam is in the 30-40% range, and for the second exam it is around 60-70%.
Key points for preparation
1st exam: Solidify your basic knowledge by studying past exam questions.
Secondary Examination: Organize your work experience and receive professional corrections (correspondence courses and seminars are effective).
Conclusion
The first-class construction management engineer certification exam is not an easy one, given the high hurdles of eligibility (work experience) and the exam content, which requires specialized knowledge and writing skills. In particular, preparing for the “experience description” section, which allows you to utilize your experience, is key to passing.
