Predicting International Baccalaureate (IB) Scores: A Comprehensive Guide for Pupils and Guardians

Schools predict International Baccalaureate (IB) scores primarily through a combination of mock exams, internal assessments, and teacher professional judgment. These predicted grades serve as an estimate of the final IB exam outcomes, used especially for university applications.

The main methods and factors include:

• Internal assessments: Schools evaluate student work across the two years of the IB Diploma Programme (DP), including essays, projects, and oral presentations that are graded internally by teachers according to IB criteria. These assessments provide ongoing insight into a student's likely performance on final exams.
• Mock exams: Practice exams, often designed to mirror the format and difficulty of IB assessments, are conducted to gauge students’ readiness and secure a more evidence-based grade prediction. These mock results are used to extrapolate expected final scores.
• Teacher expertise and professional judgment: Teachers use their knowledge of students' classroom participation, coursework quality, and improvement over time to refine predicted grades. Their judgments incorporate all the evidence available, not just raw exam scores.
• Grade boundary considerations: While schools predict grades, the IB Organization applies subject-specific grade boundaries to scaled totals (a weighted sum of component marks) after exams, which affects the final grades. However, teachers’ predictions are based on the students’ progress and component performances, anticipating these boundaries.
• Use of historical data: Some schools incorporate results from prior cohorts with similar teaching approaches or student demographics to calibrate predictions more accurately.

In summary, the prediction process synthesizes continuous assessment results, performance on mock tests, and teacher insights, aiming to forecast each student’s IB score reliably before official results are released. This prediction is important for university admissions, where predicted grades often guide conditional offers.

However, it's essential to note that predicted scores are not always accurate and can be overestimated or underestimated. Internal Assessments account for 20-30% of the final IB mark in most subjects. Some schools allow revisions to predicted scores, especially if new evidence supports an update, but this depends on timing and institutional rules.

In many schools, departments conduct moderation sessions to ensure alignment across different subjects and educators. Underpredictions of IB scores may limit university opportunities, while overpredictions of IB scores can lead to missed offers if final grades fall short. A student who steadily performs well across various formats will typically earn stronger predictions.

In many schools, students can see their predicted grades, but this depends on local policy. To secure favorable predictions, students should engage consistently, seek improvement, and treat all assessments as meaningful. Student transparency, effort, and communication with teachers are vital for influencing predicted IB scores.

Educational institutions use mock exams as a tool for evaluating student exam performance and personal growth in the context of education-and-self-development, as these practice tests provide insights into a student's readiness and serve as a foundation for predicting final IB scores. Learning from past assessments and seeking continuous improvement are crucial factors for students striving to optimize their predicted IB scores.
