If you’re an IB student applying to universities or scholarships, your predicted grades play a crucial role. These grades provide an estimate of your final IB Diploma scores and help institutions assess your potential before official results are released. But how are these predicted grades actually calculated? Let’s break it down.

What Are Predicted Grades in IB?

Predicted grades are the scores your teachers forecast you will achieve in each IB subject and core component (Extended Essay and Theory of Knowledge). They are submitted to the IB and used in university applications, early offers, and sometimes scholarships.

How Teachers Calculate Predicted Grades

There is no single IB-mandated method, but schools and teachers follow common practices based on IB expectations:

1. Performance in Class

Teachers consider your performance on:

  • Past tests, quizzes, and assignments
  • Mock exams and past papers
  • Class participation and consistency over time

2. Internal Assessment (IA) Progress

IA drafts and final submissions provide insight into your depth of understanding, research, and analytical skills. A strong IA can positively influence a predicted grade.

3. School-Based Exams

Many schools hold mock exams or trial exams (often using past IB papers) to assess readiness and predict performance under exam conditions.

4. Trends in Performance

Teachers look at your academic trajectory:

  • Are your grades improving steadily?
  • Are you consistent, or do results fluctuate?

This helps refine the prediction beyond a single data point.

5. Comparisons to IB Grade Boundaries

Teachers use historical IB grade boundaries and past student performance to align your predicted grade with IB standards. For example, if your mock exam score falls within a range that historically earned a 6, your predicted grade may reflect that.

6. Professional Judgement

Ultimately, your teacher’s professional judgement—based on experience with IB standards, past students, and their knowledge of your work—plays a major role in determining your predicted grade.

Core Component Predicted Grades

  • Extended Essay (EE): Predicted based on drafts, depth of research, critical analysis, and adherence to the criteria.
  • Theory of Knowledge (TOK): Predicted from presentation and essay drafts, as well as class discussions and tasks.

Do Predicted Grades Have to Match Final Grades?

No. Predicted grades are best estimates—they can be higher or lower than final grades. Universities understand this and consider them as part of a broader application.

Can Predicted Grades Be Challenged?

Generally, predicted grades are final once submitted. However, if you feel a grade does not reflect your performance, it’s worth having a respectful conversation with your teacher before submission deadlines.

Final Thoughts

Predicted grades are calculated using a combination of mock exams, IA performance, classwork, trends, and professional judgement. While they are important, remember they are just predictions—not guarantees. Focus on consistent effort and seek feedback to ensure your actual results match or exceed your predictions.
