How to Score a 7 on IB Internal Assessments (With Examples)
A student who knows their subject inside and out can still walk away with a 5 on their internal assessment. That's because the IA isn't marked on how much a student knows, but against a fixed set of criteria descriptors. Every internal assessment IB students submit is judged this way, which means achieving a 7 comes down to meeting each descriptor in the top band precisely, not writing something impressive.
This guide breaks down what separates a 5 from a 7, subject by subject, and includes a full IB History IA example.
Top Tips
The internal assessment (IA) is worth 20% of your final grade in most Diploma subjects, weighted directly against fixed marking criteria rather than compared to other students.
Unlike your exams, it's entirely within your control. You can plan it, draft it, get feedback, and revise before it's ever submitted. Our expert team at Little Geniuses can also help you prepare and complete your IAs with confidence.
The six most common ways students lose marks: a research question that's too broad, description instead of analysis, vague evaluation, the wrong structure for the subject, making the IA too complicated and starting too late.
Science, Maths, History and Economics IAs are built and marked completely differently. One approach never transfers cleanly across subjects.
What a 7-Worthy Research Question Looks Like
Every IB internal assessment starts with a research question, and this is where most marks are won or lost before a single word of analysis is written.
Weak: "How has social media affected teenagers?"
Strong: "To what extent did the 2023–24 phone bans in NSW public high schools affect self-reported concentration levels among Year 10 students?"
The strong version is narrow enough to investigate within the word limit, and specific enough that the student is forced to analyse rather than describe. That single shift from broad and vague to narrow and testable is usually the first thing an examiner notices in any strong IB IA example.
To do well, we also guide our students through the marking criteria and IB marker subject reports from previous years.
The 5 Mistakes That Cost Students Marks
A research question that is too broad. A topic like "the causes of World War One" can't be investigated properly in 2,200 words. A 7-level IB history IA example narrows this to one specific decision, policy, or turning point.
Being descriptive instead of analytical. Retelling what happened earns marks in the lowest bands. Explaining why it happened and what it means earns the highest.
Providing a generic evaluation. "Human error" and "small sample size" are the two phrases examiners see most often, and neither says anything specific about the actual limitations of the investigation.
Following the wrong structure for the subject. A student who writes a science lab report in the form of a history essay (or vice versa) is fighting the criteria rather than working with them.
Starting too late. IAs written in the final fortnight rarely have time for a proper draft, teacher feedback, and revision, all of which are what can move a 5 into a 7.
A strong IB IA example in any subject fixes all five of these well before the first full draft goes to a teacher. It's rarely one dramatic rewrite that lifts a mark. It will more likely be multiple small corrections, applied consistently from the first outline onward.
Why the Same IB IA Example Never Works Across Subjects
There's no single template for a top-scoring internal assessment IB assessors will recognise across every subject, because the task itself changes by subject group:
Sciences
IB science subjects require a structured investigation: a clear methodology, controlled variables, raw and processed data, and a discussion of uncertainty.
Mathematics
Mathematics is an exploration, not a report. The mark comes from how the mathematical idea is developed and reflected on, not just from a correct final answer.
History
History is a source-based investigation. The IB's most recent update restructured the history IA into three sections (historical inquiry question, sources and perspectives, and synthesis and evaluation), replacing the old standalone reflection section. It's worth 25% of the final grade at SL and 20% at HL.
Economics
Economics uses a three-commentary portfolio, each roughly 800 words and tied to a different unit of the syllabus, rather than a single long investigation.
We also recommend steering clear of using AI to generate a topic. AI topics are not original and have low personal engagement. At Little Geniuses, we work with our students to help select an original IA topic that has high personal engagement.
Getting the Support That Will Move the Needle
A 7 IA isn't about being impressive. It's a strategic exercise in meeting every criterion descriptor precisely, which is far easier with someone who's marked against those descriptors before, checking drafts against the actual criteria.
Little Geniuses’ IB tutoring in Sydney provides one-on-one sessions that map each student's research question, draft, and evaluation directly against the current mark bands, subject by subject, well before the deadline crunch hits. We also provide tutoring and guidance for passing IB exams.
The internal assessment is the one part of the IB where the outcome is in your hands. Start early, match the structure to the subject, and mark your own draft against the criteria before anyone else does.
