What is an Official Report?
An official report is a formal, structured document that presents information, findings, or data to a specific audience for a specific purpose. Reports are objective, factual, and organised logically.
Formal & objective
Professional tone, factual content, minimal personal opinion
Structured
Clear sections with headings and logical organisation
Evidence-based
Supported by data, research, observations, or facts
Purpose-driven
Written to inform, analyse, or recommend action
Reports present information clearly and professionally to help readers understand a situation, make decisions, or take action. Common types: progress reports, investigation reports, research reports, evaluation reports, recommendation reports.
Why it matters for IB
Writing reports demonstrates your ability to organise information logically, communicate professionally, and analyse data objectively — critical academic and workplace skills.
Essential Components of Reports
Every official report includes these key sections:
Report header
To, From, Date, Subject/Title
Introduction
Purpose, scope, and context of the report
Findings / body
Main information, data, or observations with headings
Analysis
Interpretation of findings and their significance
Conclusions
Summary of main points and implications
Recommendations
Suggested actions based on findings (if applicable)
Reports prioritise clarity and organisation. Use headings, bullet points, and numbered lists to make information easy to find. The goal is efficient communication, not literary style.
Standard Report Structure
Follow this proven structure for effective reports:
Header is not counted in your word total. Aim for 450–550 words across the four written sections.
Writing the Report Header
The header provides essential context at a glance. It should be clear and professional.
Standard format
Good example
Common mistakes
- Forgetting the header entirely
- Vague subjects: "Report" instead of "Report on School Recycling Programme Effectiveness"
- Informal date format: "3/15/25" instead of "15 March 2025"
- Missing recipient or sender titles
Crafting the Introduction
The introduction establishes purpose, scope, and context. Keep it concise and focused.
Purpose statement — why the report was written
"This report examines the effectiveness of the new school recycling programme implemented in September 2024."
Scope — what the report covers
"The analysis focuses on participation rates, waste reduction, and cost implications over a six-month period."
Brief context / background
"The programme was launched in response to student council recommendations to reduce campus waste by 40%."
50–80 words is sufficient. The introduction orients readers — save detailed information for the findings section.
Organising Findings Effectively
The findings section is the heart of your report. Present information logically with clear headings.
Use clear subheadings
Break content into logical sections with descriptive headings:
• Student Participation Rates · Waste Reduction Statistics · Cost Analysis
Present data clearly
"Student participation increased from 45% in September to 78% in February, representing a 73% improvement."
Use lists and bullet points
Key findings include:
• 2,300 kg of waste diverted from landfills
• 89% student satisfaction rating
• Monthly cost savings of $450
Language & Tone Guidelines
Formality level
Use: Professional, objective language
Avoid: Contractions, slang, emotional language
Example: "The data indicates" ✓ — not "It's clear that"
Voice
Use: Third person or passive voice for objectivity
Example: "The survey was conducted" or "This report examines" ✓
Not "I conducted" or "We found"
Tone
Use: Neutral, factual, confident
Avoid: Personal opinions, bias, excessive hedging
Example: "Results demonstrate significant improvement" ✓
Not "I think results are good"
Formal — good
"The data indicates a 59% reduction in single-use plastic consumption over the reporting period."
Informal — avoid
"The recycling thing is going pretty well and we're doing awesome at cutting down plastic."
Writing Strong Conclusions
Conclusions synthesise findings without introducing new information.
- Summarise key findings — briefly restate the most important points
- Highlight significance — what do the findings mean?
- Be concise — 40–60 words is typically sufficient
- Stay objective — base conclusions on evidence presented
Strong conclusion example
"The recycling programme has successfully achieved its primary objectives, with participation rates exceeding targets and waste reduction surpassing initial goals. The programme demonstrates environmental and financial benefits, though some implementation challenges remain. Overall, the data supports continued investment in the initiative."
(48 words)Strong
Summarises specific findings · highlights significance · objective tone · based on evidence
Weak
"In conclusion, recycling is good for the environment. The school should keep doing it because it helps."
Vague, informal, unsupportedMaking Effective Recommendations
Recommendations are actionable suggestions based on your findings.
Specific & actionable
Strong: "Implement monthly training sessions for new recycling volunteers starting in April 2025."
Weak: "Provide more training."
Based on evidence
"Given the 15% participation gap in Grade 9, targeted awareness campaigns should be developed for younger students."
Realistic & feasible
"Expand recycling stations to three additional locations using existing infrastructure."
Use numbered lists for recommendations. Typically include 3–5 suggestions, each with enough specific detail to be actionable.

Subject: Evaluation Report on Campus Plastic Reduction Initiative
Introduction
This report evaluates the effectiveness of the campus plastic reduction initiative launched in March 2025. The analysis examines plastic usage data, student behaviour changes, and cost implications over a seven-month period. The initiative aimed to reduce single-use plastic consumption by 60% through reusable container programmes and water bottle refill stations.
Findings
Plastic Usage Reduction
Data collected from campus vendors indicates significant progress toward reduction goals. Single-use plastic bottle purchases decreased from an average of 2,400 units monthly (March) to 980 units monthly (September), representing a 59% reduction. Similarly, plastic utensil usage declined by 67%, from 8,500 items per month to 2,800 items.
Student Participation and Behaviour
Survey responses from 450 students reveal strong engagement with the initiative. Key findings include:
- 73% of students now regularly carry reusable water bottles
- 84% report awareness of plastic reduction goals
- 62% participate in the reusable container programme
- 91% support continuing the initiative
Financial and Operational Impact
The initiative has generated measurable cost benefits. Reduced waste collection fees save approximately $340 monthly, while revenue from reusable container deposits totals $280 monthly. However, installation and maintenance of water refill stations cost $4,500 initially, with ongoing monthly maintenance expenses of $120.
Challenges Identified
Several obstacles have emerged during implementation. The reusable container return rate stands at only 78%, resulting in inventory shortages. Additionally, two refill stations experienced technical failures requiring repairs, and participation rates vary significantly across different campus buildings.
Conclusion
The plastic reduction initiative has largely achieved its objectives, with usage declining 59% and strong student support demonstrated. While financial benefits offset most operational costs, equipment maintenance and inconsistent participation present ongoing challenges. The programme's success warrants continuation with targeted improvements.
Recommendations
Based on these findings, the following actions are recommended:
- Implement a deposit incentive system to increase reusable container returns to 90% by January 2026
- Establish a preventative maintenance schedule for refill stations to minimise equipment failures
- Launch targeted awareness campaigns in buildings with participation rates below 50%
- Expand the reusable container programme to include additional vendors by March 2026
- Conduct quarterly evaluations to monitor progress and address emerging challenges
Analysing the Example
What makes this report effective:
Clear, complete information about sender, recipient, date, and a specific subject line.
Logical flow with distinct sections and descriptive subheadings (Plastic Usage Reduction, Student Participation, Financial Impact, Challenges).
Concrete numbers throughout: "2,400 units to 980 units," "59% reduction," "450 students surveyed," "$340 monthly savings."
Formal, neutral language without personal opinions or emotional appeals throughout.
Each recommendation links directly to specific findings and includes actionable detail (target percentages, dates).
Presents both successes (59% reduction, 91% support) and challenges (78% return rate, equipment failures) objectively.
Common Mistakes to Avoid
Missing or incomplete header
Starting directly with "This report is about…" without proper formatting. Always include To, From, Date, and Subject.
Using informal language
"The recycling thing is going pretty well" or "We're doing awesome." Maintain professional, objective tone throughout.
Vague or unsupported claims
"Many students participated" or "Results were good." Always provide specific numbers and data.
Poor organisation
Long paragraphs without headings or logical structure. Use clear sections with descriptive headings.
Personal opinions as facts
"I think the programme is great" or "Everyone loves it." Base statements on evidence, not personal feelings.
Unrealistic recommendations
"Build a new recycling facility" without considering budget. Ensure recommendations are practical and feasible.

Revision Task 2: Transform Informal to Formal
Rewrite these sentences formally
1. "We asked a bunch of students what they thought about the new schedule and most of them said it's pretty good."
2. "I think we should definitely get more computers because everyone's always complaining about not having enough."
3. "The club's doing awesome! Lots of people joined and we're having a great time."
1. "A survey of 250 students revealed that 73% expressed satisfaction with the revised schedule, with 18% neutral and 9% dissatisfied."
2. "Student feedback indicates insufficient computer access, with 68% of respondents reporting wait times exceeding 20 minutes during peak hours. Expanding computer lab capacity by 12 units would address this documented need."
3. "Club membership increased 127% from 22 members in September to 50 members in March, exceeding growth projections. Retention rates remain high at 94%."
Revision Task 3: Write a Findings Section
Organise and present this data
Scenario: You surveyed 300 students about the school cafeteria. Results:
- 67% satisfied with food quality · 21% neutral · 12% dissatisfied
- 45% eat in cafeteria daily · 30% 2–3 times weekly · 25% rarely/never
- Main complaints: long wait times (78%) · limited vegetarian options (54%) · high prices (62%)
- Most popular items: pizza (82%) · sandwiches (71%) · salad bar (43%)
- 83% want healthier options · 76% want faster service
Write a structured findings section (200–250 words) with 2–3 clear subheadings:
Overall Satisfaction and Usage Patterns
Survey responses from 300 students indicate moderate satisfaction with cafeteria services. Approximately two-thirds (67%) reported satisfaction with food quality, while 21% expressed neutral opinions and 12% dissatisfaction. Usage patterns reveal that 45% of students utilise the cafeteria daily, 30% eat there 2–3 times weekly, and 25% rarely or never purchase cafeteria meals.
Primary Concerns and Complaints
Three main issues emerged from student feedback. Wait times represent the most significant concern, cited by 78% of respondents. Price concerns affect 62% of students, while 54% identified limited vegetarian options as problematic. These factors likely contribute to the relatively low daily usage rate.
Food Preferences and Desired Improvements
Popular menu items include pizza (82% approval), sandwiches (71%), and the salad bar (43%). Student recommendations emphasise healthier options (83% support) and faster service (76% priority). These preferences suggest strong demand for menu expansion alongside efficiency improvements.
(203 words)Revision Task 4: Write Recommendations
Create actionable recommendations
Based on the cafeteria findings above, write 4–5 specific, evidence-based recommendations (80–100 words total). Each should be actionable and linked to the data.
- Implement an express ordering system using mobile apps to reduce wait times by 40%, addressing the primary concern of 78% of students
- Expand vegetarian menu options from three to seven daily choices, responding to requests from 54% of respondents
- Introduce a healthy meal combo pricing strategy to address cost concerns while promoting nutritious options
- Add two serving stations during peak lunch hours (12:00–13:00) to decrease congestion
- Conduct quarterly menu satisfaction surveys to monitor improvement and adjust offerings based on ongoing student feedback
