Competition metrics

How results are calculated:

We have carefully considered how to rank our organisations and have decided that the fairest way to do this is by looking at the number of questions answered per student. This is to reflect the range in organisation size, even within a specific category.  

There are many ways to measure usage and you may wish to do it differently for your own competitions. At CENTURY, we calculate the student user base to get a fair balance between those organisations with a wide but less intensive use and those where only a small proportion of students use the platform extensively. 

What’s Measured?

Your organisation’s weekly score is based on two key metrics:

1. Nuggets per Active Student: The average number of nuggets completed by active students

2. Engagement Percentage: This measures how many of your students are active, in proportion to your organisation’s overall student base.

Key Factors and Fairness:

To ensure fairness, here’s how we make the calculations meaningful:

1. Cap on repeated nuggets: We want to reward genuine engagement; to ensure this, nugget attempts per student is capped at 10 (i.e. if a student has repeated the same nugget 15 times, we’ll only capture the first 10 attempts)

2. Balancing scores by active participation: If your organisation has a high percentage of engaged students, this increases your score. We use the proportion of active students as a multiplier in your ranking, so high engagement from your student body really makes a difference.

3. Category-based rankings: Each organisation is grouped into a category based on comparable characteristics. Your rank within your category allows you to compete fairly with peers at a similar level.

Ranking Example

Imagine two organisations with similar average nuggets completed per active student, but one has a higher percentage of engaged students. The organisation with more engaged students will receive a higher score and better ranking because it’s actively involving more of its students. We believe this reflects the true spirit of engagement.

Weekly Feedback and Transparency

Each week, we’ll share your organisation’s cumulative nuggets completed since the start of the competition indicating your relative position within your category. This feedback gives you insight into where you stand and what progress you might aim for.

Glossary:

Percentage ranking: This is a metric we use to inform you of your position. It is based upon the average questions answered by your user base, compared to others from within your category. We believe it is a more informative metric to help understand your position within a larger dataset, making it easier to compare and interpret results.

Overall questions answered: This is the rounded total number of questions answered by students in your organisation within each specified week. This includes all answered questions from within fully completed nuggets only and does not include skipped questions. This is also limited to 10 attempts of each individual nugget per student.

Average questions answered: This is calculated by dividing the number of overall questions answered by your user base.

User base: This is based upon the number of active students who have completed a nugget during the competition and the minimum/maximum potential number of students that could access CENTURY.

Category: This is the grouping of organisations according to the number of active students and key stage/organisation type.

We look forward to seeing your participation and celebrating high engagement. Best of luck!
