Understand the IB IA Timeline for 2025

The success of your IB journey depends largely on understanding and respecting the Internal Assessment submission deadlines. For 2025 candidates, knowing these timelines is especially crucial as you map out your academic year.

Key dates for May and November sessions

The IB operates on a dual-session calendar, with exams and assessment submissions happening twice yearly. This creates two distinct timelines you need to be aware of:

May 2025 Session Timeline:

• September 2024: Initial IA topics should be selected and approved by teachers
• November-December 2024: First drafts due for most subjects
• January 2025: Revised drafts with teacher feedback incorporated
• February 15-28, 2025: Final IA submissions to teachers for most subjects
• March 15, 2025: School deadline for uploading IA samples to IB
• April 20, 2025: Final IB deadline for IA sample submissions

November 2025 Session Timeline:

• March 2025: IA topics selection and approval
• May-June 2025: First draft submissions
• July 2025: Feedback incorporation and revisions
• August 15-30, 2025: Final submissions to teachers
• September 15, 2025: School deadline for uploading samples
• October 20, 2025: Final IB deadline for sample submissions

Each subject has slightly different requirements, but these general timelines apply to most Internal Assessments. Sciences, for example, typically require lab work completion earlier in the timeline, whereas Language B written assignments might have more flexibility.

Difference between school and IB deadlines

One of the most common mistakes I see students make is confusing school deadlines with IB deadlines. This confusion can lead to serious consequences.

School deadlines are typically set 3-4 weeks before the official IB deadlines. Your teachers aren’t simply being difficult—there are important reasons for this gap:

1. Quality assurance: Teachers need time to verify that all submission requirements are met and nothing is missing.
2. Authentication: Your work must be verified as your own, which requires teachers to review your progress throughout.
3. Selection process: Not all IAs are sent to the IB—only a sample. Schools need time to select and prepare these samples.
4. Technical buffer: Uploading materials to the IB platform takes time, and technical issues may arise.

The official IB deadlines are absolutely final. Unlike some school deadlines that might have some flexibility, missing an IB deadline means your work won’t be assessed, potentially preventing you from receiving your diploma.

Additionally, school deadlines are typically set for entire classes, whereas the final IB deadlines apply to the samples selected. Your teacher might set different internal deadlines for different components—for example, your History IA might be due earlier than your Math IA to help manage the workload.

Understanding this dual deadline system is fundamental to planning your IB journey. I always advise my students to treat school deadlines as the actual final deadlines—this way, you’ll never risk missing the critical IB submission dates.

Start Early: Planning Your IA in the First Month

The first month of your IB Internal Assessment journey is critical—it sets the foundation for everything that follows. Starting early doesn’t just mean working ahead; it means making smart decisions that will shape your entire IA experience.

Choose your IA topic and research question

Selecting the right topic is arguably the most important decision in your IA journey. During the first month, I recommend following this process:

1. Review the assessment criteria thoroughly for your specific subject
2. Brainstorm 3-5 potential topics that genuinely interest you
3. Consult subject guidelines for specific requirements and limitations
4. Meet with your subject teacher to discuss feasibility
5. Narrow down to your final choice based on resources and time constraints

When formulating your research question, aim for specificity and clarity. A well-crafted research question should be:

• Focused enough to be completed within the word count
• Measurable with available resources and methods
• Aligned with assessment criteria
• Interesting enough to sustain your motivation

Furthermore, check past exemplars to understand what successful IAs look like in your subject. Your teacher likely has access to these resources. Many students who start with vague or overly ambitious topics struggle to meet deadlines later.

Set personal deadlines for drafts and feedback

Once your topic is approved, immediately create a personal timeline that works backward from your school’s Internal Assessment submission deadlines. This approach provides structure and prevents last-minute panic.

Your first-month timeline should include:

Primary deadlines:

• Research completion date (at least 2 months before final submission)
• First draft completion (typically 6-8 weeks before school deadline)
• Teacher feedback sessions (schedule at least 2-3 throughout the process)
• Final draft submission (1 week before school deadline)

Secondary deadlines:

• Weekly research milestones
• Outline completion
• Methodology finalization
• Data collection completion

Consequently, you’ll need to schedule specific days for working on your IA. Block these times in your calendar and treat them as non-negotiable appointments.

Additionally, build buffer time into your schedule—approximately 20% more time than you think you’ll need. This extra time accounts for unexpected setbacks, illness, or competing priorities from other subjects.

Most importantly, schedule feedback sessions with your teacher early. Teachers often become overwhelmed as deadlines approach, making it difficult to get quality feedback. Securing these meetings in advance ensures you’ll receive guidance when you need it most.

Remember that these timelines are personal commitments. Unlike official Internal Assessment submission deadlines, these are flexible—but treating them as firm commitments will significantly reduce your stress levels as official deadlines approach.

Finally, share your timeline with someone who can help hold you accountable—whether that’s a parent, study partner, or mentor. External accountability often provides the motivation needed to stay on track during those busy first weeks.

Work in Phases: Research, Drafting, and Revisions

Breaking down your Internal Assessment into manageable phases is the key to maintaining quality while meeting submission deadlines. Once you’ve selected your topic and created a timeline, it’s time to execute your plan with precision and discipline.

Break your IA into weekly tasks

Success hinges on transforming your IA from a monumental project into bite-sized weekly assignments. I recommend creating a weekly task schedule that aligns with your subject’s specific requirements:

For science subjects (Biology, Chemistry, Physics):

• Week 1-2: Complete background research and finalize methodology
• Week 3-4: Conduct experiments and collect data
• Week 5-6: Analyze results and create visual representations
• Week 7-8: Write introduction and methodology sections
• Week 9-10: Complete results, analysis, and evaluation sections

For humanities (History, Economics, Business):

• Week 1-2: Gather primary and secondary sources
• Week 3-4: Analyze sources and develop your argument
• Week 5-6: Create outline with supporting evidence
• Week 7-8: Write first half of the assessment
• Week 9-10: Complete second half and revise

Track your progress using a simple checklist or digital tool. Each weekend, review what you’ve accomplished and adjust the upcoming week’s tasks accordingly. This approach prevents the overwhelming feeling that leads to procrastination.

Allocate time for teacher feedback

Teacher feedback is invaluable, yet many students make the mistake of seeking it too late. Instead:

1. Schedule at least three feedback sessions throughout your IA process:
   • After completing your research/methodology
   • After drafting approximately 50% of your IA
   • After completing your full draft
2. Prepare specific questions for each feedback session to maximize its value.
3. Allow 1-2 weeks between receiving feedback and your final submission deadline.

Remember that teachers have multiple students to assist, so request feedback appointments at least two weeks in advance. This foresight ensures you’ll receive guidance when you need it most.

Avoid cramming by using a 3-phase model

The 3-phase model provides structure to your IA journey while ensuring quality work:

Phase 1: Research and Planning (40% of your allocated time)
Focus on gathering information, understanding concepts, and organizing your approach. This phase establishes the foundation for everything that follows and prevents mid-project changes that can derail your timeline.

Phase 2: Drafting and Development (30% of your allocated time)
Create your first complete draft without obsessing over perfection. The goal is to translate your research into a coherent document that addresses all assessment criteria.

Phase 3: Refinement and Polishing (30% of your allocated time)
Use this time to incorporate feedback, strengthen weak areas, ensure proper citations, and perfect your formatting. Many students underestimate how time-consuming this phase can be.

Throughout these phases, maintain a work diary noting challenges and breakthroughs. This practice not only helps you track progress but also provides valuable information if you need to discuss extensions with your coordinator.

Always remember that quality IAs develop gradually through iterative improvements rather than in marathon sessions. By working consistently across these phases, you’ll produce higher-quality work while effectively managing Internal Assessment submission deadlines.

Use Tools to Stay on Track

Technology can be your greatest ally in meeting Internal Assessment submission deadlines. With the right digital tools and systems, I find that students turn chaotic workloads into manageable processes.

Calendar apps and reminders

The ideal calendar system for tracking Internal Assessment deadlines combines both visual organization and proactive notifications. Since your brain processes visual information 60,000 times faster than text, color-coding your calendar is remarkably effective.

I recommend setting up your calendar with these specific elements:

• Color differentiation – Assign distinct colors to each subject’s IA milestones (green for Biology, blue for Economics, etc.)
• Backward planning – Start from your final submission date and mark intermediate deadlines
• Buffer zones – Block 2-3 days before each deadline as protected “completion time”
• Recurring work sessions – Schedule consistent weekly IA work blocks

Google Calendar works exceptionally well for IB students because it syncs across devices and allows for shared calendars with study groups. Microsoft Outlook offers similar functionality with more robust reminder options.

For reminders, don’t rely solely on standard notifications. Instead, implement a multi-level reminder system:

1. Initial reminder (1 week before)
2. Secondary reminder (3 days before)
3. Final reminder (24 hours before)

This graduated approach prevents deadline shock while giving you time to adjust if you’re falling behind.

Tracking progress with checklists

Checklists transform overwhelming projects into concrete, actionable steps. Though simple, they provide psychological satisfaction when items are completed, releasing dopamine that motivates continued progress.

For effective IA progress tracking, implement these checklist principles:

1. Break down each IA component into tasks requiring no more than 30-45 minutes
2. Include verification steps (e.g., “Check citations against IB guidelines”)
3. Add completion percentages to visualize overall progress
4. Schedule regular checklist reviews to assess your pace

Digital tools like Todoist, Notion, or Trello excel at managing these checklists, particularly because they allow you to attach files, deadlines, and priority levels to each task. Notion, in particular, offers templates specifically designed for academic projects.

Nevertheless, don’t underestimate physical tracking methods. Many students find that maintaining a dedicated IA journal or using a visual task board on their wall provides tangible satisfaction that digital tools cannot match.

Regardless of which tools you choose, consistency matters more than sophistication. The most elaborate planning system fails if you don’t check it regularly. Therefore, establish a habit of reviewing your calendars and checklists at the same time each day – ideally both morning and evening.

Handle Setbacks Without Missing Deadlines

Even with perfect planning, obstacles in your IB journey are inevitable. How you respond to these challenges ultimately determines whether you meet your Internal Assessment submission deadlines.

What to do if you’re falling behind

If you notice yourself slipping behind schedule, take immediate action rather than hoping to catch up later:

1. Reassess your timeline – First and foremost, review your remaining work against available time. Create a revised schedule that prioritizes the highest-value components (those worth most marks).
2. Identify the specific bottleneck – Is research taking longer than expected? Are you struggling with analysis? Pinpoint exactly where you’re stuck to address the root cause.
3. Eliminate non-essential activities – Temporarily reduce commitments in other areas. This might mean scaling back extracurriculars or social activities for a short period.
4. Apply the Pomodoro technique – Work in focused 25-minute intervals with 5-minute breaks to maximize productivity without burnout.
5. Seek peer support – Form study groups where you can hold each other accountable or exchange feedback on drafts.

When to talk to your teacher or coordinator

Granted, some situations require professional intervention. Approach your teachers promptly if:

• You’re more than a week behind your personal timeline
• You encounter research obstacles beyond your control
• You’re experiencing health issues or personal emergencies
• You’re struggling with conceptual understanding despite research efforts

Prior to meeting with your teacher, prepare by:

• Documenting your current progress
• Creating a list of specific questions or challenges
• Drafting a revised timeline proposal

Obviously, approach these conversations professionally. Request the meeting well in advance, arrive with organized materials, and maintain a solution-focused attitude.

Remember that teachers would much rather help you early than receive substandard work at the deadline. Generally speaking, they can offer extensions for school deadlines but have no control over official IB submission dates.

In extreme circumstances involving serious illness or emergencies, your IB coordinator can request special consideration from the IB, but this requires formal documentation and is never guaranteed.

Conclusion

Meeting Internal Assessment deadlines requires careful planning, consistent effort, and the right strategies. Throughout this guide, I’ve shared proven methods that have helped countless IB students submit quality work on time.

Success starts with understanding your timeline and respecting both school and IB deadlines. Starting early gives you the advantage of selecting the best topic and creating a realistic schedule. Additionally, breaking down your work into research, drafting, and revision phases makes the entire process more manageable.
