IB Jargon Demystified: A Parent's Guide

Welcome to the International Baccalaureate! As your child begins this challenging and rewarding journey, you'll probably start hearing a lot of acronyms: TOK, IA, HL, SL. It can feel like learning a new language. This guide is designed to be your translator, helping you understand the key terms so you can better support your child and feel confident during conversations with their school.

Think of us as your personal tutor. Let's break down exactly what these terms mean for your child's education.

What is TOK (Theory of Knowledge)?

In simple terms: TOK isn't a typical subject with facts to memorize. It's a critical thinking class that explores the very nature of knowledge. The central question is, "How do we know what we claim to know?"

Students don't learn *what* to think, but *how* to think. They'll explore different ways of knowing (like reason, emotion, and language) and different areas of knowledge (like history, the arts, and natural sciences). This helps them connect their learning across all their IB subjects.

• Why it matters: TOK develops analytical and argumentation skills that are invaluable for university and beyond. It teaches students to challenge assumptions and understand diverse perspectives.
• How it's assessed: There are two parts: a 1,600-word essay on a prescribed title and an "exhibition" where students reflect on how TOK manifests in the real world.
• The Core Points: TOK is a mandatory "core" component of the IB Diploma. A good grade, combined with the Extended Essay (EE) grade, can add up to three bonus points to their final IB score.

HL vs. SL: What's the Difference?

Every IB Diploma student takes six subjects. They choose three to study at Higher Level (HL) and three at Standard Level (SL). The right balance is key to a manageable workload and a strong university application.

Decoding the IA (Internal Assessment)

The IA is a major, research-based project that students complete for nearly every subject. It's their chance to dive deep into a topic that genuinely interests them, applying the skills they've learned in class. The IA is a huge part of the IB philosophy, promoting independent learning and research skills.

What it looks like in practice:

• In Sciences: A hands-on experimental investigation and lab report.
• In Mathematics: A written exploration of a mathematical concept or problem.
• In History: A historical investigation essay on a specific question.
• In Languages: An oral presentation and analysis.

Crucially, the IA makes up a significant portion of the final grade for a subject, typically 20-30%. It is marked by their classroom teacher and then moderated by the IB to ensure global standards are consistent.

The Importance of Predicted Grades

Predicted Grades are the grades the school estimates your child is likely to achieve in their final exams. They are not a guess; they are a professional judgment based on solid evidence.

Why they are so critical: For university applications (especially to the UK, USA, and Europe), Predicted Grades are everything. Universities use these grades to decide whether to make a conditional offer of admission, as applications are often submitted before final IB exams are taken.

How they are determined:

• Performance in mock exams.
• Scores on Internal Assessments (IAs).
• Consistency and effort shown in class tests, homework, and participation throughout the two years.

Schools typically finalize these grades in the autumn of the final year (DP2). A strong set of predictions is essential for opening doors to top universities. It’s important to understand that a university offer is often conditional on achieving final grades that are close to the predicted ones.
