Summative assessment
Summative assessment is assessment used to measure and report what a student has achieved at the end of a period of teaching, such as an end-of-unit test, a mock or a public examination.
What is summative assessment?
Summative assessment measures and reports what a student has achieved at the end of a period of teaching. End-of-unit tests, mock exams and public examinations are typical examples. Its output is a mark or grade intended to summarise attainment, rather than to guide the next stage of teaching.
Summative assessment answers the question "what has been learned?" at a point where an account is required - the end of a unit, a term, a course. Because the result is reported and often carries consequences, summative assessment tends to be more formal, more standardised and more carefully moderated than assessment used day to day.
Why it needs to be consistent
The moment a mark is reported, its consistency matters. A grade that depends on which teacher marked the work is unfair to students and misleading to anyone using it - for setting, for intervention, for a reference. This is why departments standardise before marking summative assessments and moderate afterwards, and why exam boards invest heavily in both.
Summative evidence used formatively
A summative assessment is not formatively useless once the grade is recorded. The richest diagnostic evidence a department gets each year usually comes from mocks, because they are long, broad and taken seriously. Breaking those results down by question and by assessment objective turns a reporting exercise into a teaching plan.
Key takeaways
- Summative assessment measures and reports attainment at the end of a period of teaching.
- Because results are reported, consistency between markers matters more than in day-to-day assessment.
- Standardisation and moderation are how departments protect that consistency.
- Summative results are also the richest source of diagnostic evidence a department collects.
Frequently asked questions
Is a mock exam formative or summative?
Both, depending on what is done with it. Reporting a grade from it is summative use; analysing which questions and objectives lost marks, and reteaching accordingly, is formative use. Mocks are unusual in how well they serve both purposes, because they are broad and students take them seriously.
How often should summative assessment happen?
There is no single right answer, and it varies by school and subject. The practical constraint is that each summative assessment carries a real cost in teaching time, marking and moderation - so the question worth asking is what decision each one informs, and whether that decision needs it.
Related terms
Formative assessment
Formative assessment is assessment used during learning to find out what students can and cannot yet do, so that teaching can be adjusted in response.
Grade boundaries
Grade boundaries are the minimum marks required for each grade in a qualification, set after marking so that a grade means the same thing from one year to the next.
Non-exam assessment
Non-exam assessment is work that counts towards a qualification but is completed outside examination conditions - coursework, practical or project work - usually marked in school and moderated by the exam board.
Moderation
Moderation is the process by which teachers compare samples of marked work to check that a mark scheme has been applied consistently, so the same work would receive the same mark whoever marked it.
