IB History IA Grader — Free AI Feedback on Your Historical Investigation

IBLens grades your IB History Internal Assessment (Historical Investigation) against the official IB History IA rubric. Get criterion-by-criterion feedback on your Section A, B, and C in 60 seconds. A free preview is included; the full report is $4.99.

IB History IA rubric: three sections (25 marks)

Section A — Identification and Evaluation of Sources (6 marks): You select two primary or secondary sources and evaluate their origin, purpose, value, and limitation (OPVL). IBLens checks whether your OPVL analysis goes beyond surface-level description and genuinely connects to your investigation's question.
Section B — Investigation (15 marks): Your historical argument, supported by evidence from a range of sources. IBLens checks whether your argument is consistently analytical rather than narrative, whether counter-arguments are addressed, and whether evidence directly supports your claims.
Section C — Reflection (4 marks): Your reflection on the methods and challenges historians face. IBLens checks whether your reflection is specific to your investigation and demonstrates genuine understanding of historical methodology.

Common IB History IA mistakes IBLens catches

Descriptive Section B: Narrating what happened instead of arguing why or how. Examiners want analytical writing — every paragraph should advance your argument, not retell events.
Surface-level OPVL: Saying a source is "biased because the author has an opinion" without specifying how the bias affects its value or limitation for your specific investigation.
Weak research question: Questions like "What caused World War I?" are too broad. A strong History IA research question is specific, debatable, and historically significant.
Generic reflection: Section C should reference specific methodological challenges you encountered in your own investigation — not generic statements about what historians do.
Over-reliance on one type of source: Using only secondary sources, or only sources from one perspective, limits your Section B marks.
