Everything is worked out in your browser; no name, no duration and no arrangement is sent to a server. In an Evalmee exam, extra time is set candidate by candidate and each paper is submitted automatically at the right time. ## How to calculate extra time ### Enter the length of the paper In hours and minutes, as printed on the timetable: one hour, one hour forty-five, three hours. Add the start time if you want to read the finish time directly rather than the duration alone. ### Pick the extra time granted Twenty-five or fifty per cent under JCQ access arrangements, fifty per cent for time and a half, one hundred per cent for double time, or any percentage stated in the candidate's arrangement. Supervised rest breaks are entered separately, in minutes, because they are added flat rather than extended. ### Read the extended duration and the finish time The result appears straight away, with the minutes added and the rounding rule used. The candidate list, opened under the calculation, applies the same calculation to a whole room and produces the table you hand to the invigilator. ## Extra time table: 25 %, 33 %, 50 % and 100 % The lengths of paper that come up most often, crossed with the percentages most often granted. The 33 % column is the French statutory third rather than a literal thirty-three per cent, which is why a three-hour paper comes out at exactly four hours instead of three hours fifty-nine. Two of these rows do not land on a round number: an hour and a half with 25 % extra time runs to 1 h 53, not 1 h 52 or 1 h 55. That is the rounding published extra-time tables use — nearest minute, half a minute rounding up — and matching it matters, because a room that displays a different figure from the centre's paperwork has an argument on its hands. The tool can round up to the next five minutes instead when the finish time has to be read out. | Length of paper | 25 % extra time | 33 % (statutory third) | 50 % extra time | 100 % (double time) | | --- | --- | --- | --- | --- | | 1 h 00 | 1 h 15 | 1 h 20 | 1 h 30 | 2 h 00 | | 1 h 30 | 1 h 53 | 2 h 00 | 2 h 15 | 3 h 00 | | 2 h 00 | 2 h 30 | 2 h 40 | 3 h 00 | 4 h 00 | | 3 h 00 | 3 h 45 | 4 h 00 | 4 h 30 | 6 h 00 | | 4 h 00 | 5 h 00 | 5 h 20 | 6 h 00 | 8 h 00 | ## Access arrangements: who is entitled to extra time? Extra time is one of the access arrangements available to a candidate with a disability, a learning difficulty or a temporary injury. In the United Kingdom the conditions, the evidence required and the deadlines are set out by the JCQ in its Access Arrangements and Reasonable Adjustments booklet, which the centre's exams officer applies; in the United States they follow from a candidate's IEP, 504 plan or ADA accommodation. In France, the [tiers-temps](https://evalmee.com/en/assessment-glossary/#tiers-temps-french-statutory-extra-exam-time) is a statutory third of the time normally allowed, one of the [aménagements d'épreuves](https://evalmee.com/en/assessment-glossary/#amenagements-d-epreuves-french-exam-access-arrangements) the authority organising the exam may grant. This page works out durations; it does not decide who is entitled to what, and it interprets no regulation. Read the rules at their source — jcq.org.uk for access arrangements and supervised rest breaks, the awarding body for anything specific to a qualification — and, where the arrangement a candidate has been granted differs from what you read here, the arrangement is what counts. ## Preparing the candidate list for invigilators The candidate list, opened under the calculation, expects what an exams office already has: a column of names and, beside each, the arrangement granted. Paste it as `Name; 25`, one line per candidate, or add the rows one by one. The table then gives each candidate an extended duration and a finish time, in the order you entered them — the order the list will be read in the room. An arrangement is sometimes written in minutes rather than as a percentage: type `20 min` and exactly those minutes are added, with no conversion. Supervised rest breaks go in their own column and are added flat. The print button outputs the list on its own, without the rest of the page: twelve candidates fit on one A4 sheet, which is the size of a typical separate room. Names stay in your browser. They are never stored, not even in local storage, and disappear when the page is reloaded; the CSV export writes them to a file only you receive. For the room itself, the [exam clock](https://evalmee.com/en/tools/exam-clock/) takes the start time, the duration and the percentages from this page and projects a clock with one finish time per group. ## The extra time formula Extra time multiplies the length of the paper by one plus the percentage granted, and supervised rest breaks are then added flat. A third — the French tiers-temps — is the same formula with four thirds: one hour becomes 1 h 20, an hour and a half becomes 2 h 00, three hours become 4 h 00. ``` extended duration = length × (1 + extra time ÷ 100) + rest breaks statutory third = length × 4/3 Example: a 1 h 45 paper, 25 % extra time, a 10-minute rest break extended duration = 105 × 1.25 = 131.25 → 131 min, + 10 min = 2 h 21 finish time = 09:00 + 2 h 21 = 11:21 ``` ## Frequently asked questions ### How do I calculate 25 % extra time? Multiply the length of the paper by 1.25. A ninety-minute paper becomes 112.5 minutes, which rounds to 1 h 53; a 1 h 45 paper becomes 2 h 11. If the paper starts at 09:00, a candidate with 25 % extra time on a ninety-minute paper finishes at 10:53 while the rest of the room finishes at 10:30. ### How is extra time rounded? To the nearest minute, with half a minute rounding up — the rule the published extra-time tables follow, so that the figure on your wall matches the figure on the centre's paperwork. A ninety-minute paper with 25 % extra time is therefore 1 h 53. A centre that prefers to announce a round finish time can round up to the next five minutes instead. ### Do supervised rest breaks count towards extra time? No. A supervised rest break is time the candidate does not spend working, so it is added flat to the extended duration rather than extended in turn. Ten minutes of rest stay ten minutes whether 25 %, a third or 50 % was granted. Extending the break too would hand back time the arrangement never granted. ### What is the difference between 25 % extra time and time and a half? Twenty-five per cent adds a quarter of the paper's length: two hours become 2 h 30. Time and a half — fifty per cent — adds half: the same paper becomes three hours. Double time adds the whole length again, giving four hours. The French statutory tiers-temps sits between the first two, adding an exact third. ### How do I display the extra-time finish in the exam room? Work out the finish times here, then open the exam clock from the button provided: it carries over the start time, the length of the paper and the percentages, and projects a full-screen clock with one row per group. Candidates then see their own finish time without an invigilator having to repeat it. ### Can I calculate extra time for several candidates at once? Yes: that is what the candidate list under the calculation is for. Paste a list in the form `Name; percentage`, one line per candidate, and the table gives each of them an extended duration and a finish time. It prints as it stands for invigilators and exports to CSV. The names never leave your browser. ## Other tools ## And when the exam is online?
