How Many Internal Assessments Are There in Total? A Full Breakdown for IB Students

• IA: Written investigation or research project (~1,500–2,200 words)

Group 4: Sciences

• Biology, Chemistry, Physics, Environmental Systems and Societies
  • IA: Scientific investigation or experiment report (up to 12 pages)

Group 5: Mathematics

• Math: Analysis and Approaches (AA) and Math: Applications and Interpretation (AI)
  • IA: Mathematical exploration (~6–12 pages of analysis and reflection)

Group 6: The Arts

• Visual Arts, Music, Theatre, Film, Dance
  • IA: Varies by subject (e.g., portfolio, performance commentary, composition)

Every subject has 1 IA, regardless of SL or HL. However, HL students usually have additional depth or complexity in their assessment tasks.

Summary: How Many IAs Does One IB Student Submit?

Assuming you’re a full IB Diploma student:

• You take 6 subjects (3 HL and 3 SL)
• Each subject has 1 IA
• Therefore, you’ll submit 6 Internal Assessments in total

This is in addition to your Extended Essay (EE) and TOK Essay & Exhibition, which are separate core components.

In total, expect to complete 9 major submissions across your IB Diploma journey.

How Internal Assessments Are Graded and Their Weight

Internal Assessments count for 20–30% of your final grade in most subjects.

Here’s how they’re assessed:

• Teachers mark your IA using IB-assigned rubrics
• A sample of these is moderated by external examiners
• If discrepancies are found, all grades may be adjusted

This makes it essential to follow rubrics closely, stay within word/page limits, and meet deadlines.

Managing Multiple IAs Without Burnout

Multiple IAs can feel overwhelming—especially when deadlines bunch together. Here’s how to stay ahead:

• Start early: Many IAs begin in Year 1 or early Year 2
• Use a calendar: Plot deadlines and progress check-ins across months
• Break IAs into stages: Topic selection, research, drafts, feedback, final edits
• Rotate focus: Don’t try to finish all IAs at once—work on 1–2 each month
• Communicate with teachers: Ask for interim feedback to avoid last-minute issues

Good IA management often determines how smoothly your final IB year goes.

Common IA Mistakes and How to Avoid Them

Avoid these traps:

• Procrastinating: Waiting until the last minute kills quality
• Choosing vague topics: Be specific and focused to stay on track
• Ignoring rubrics: These determine your score—use them like a checklist
• Skipping feedback: Feedback can raise your mark by a full grade
• Not citing sources: Plagiarism can result in automatic disqualification

Stay organized, seek clarity early, and treat each IA as a long-term project.

FAQs on IB Internal Assessments

Q1: Are IAs easier than final exams?
They’re more flexible and less pressured, but require more independent effort and attention to detail.

Q2: Can I redo an IA if I’m not happy with my grade?
No—once submitted to the IB, it’s final. However, drafts can be improved before the official deadline.

Q3: Do SL and HL IAs differ in difficulty?
Not always, but HL students may have to demonstrate deeper analysis or broader knowledge.

Q4: What happens if I miss an IA deadline?
You risk failing that subject or the full diploma. Always inform your coordinator and plan ahead.

Q5: Are group IAs allowed?
No—IB IAs are individual assessments. Group work can happen in labs or prep, but submissions are solo.

Q6: Which IA is the most time-consuming?
It varies, but many students find Sciences and Maths IAs take the longest due to data analysis and precise formatting.
