How to do the Kraepelin test means adding two adjacent numbers in a column, then writing the unit digit of the result between them, working from the bottom of the column upward. When the examiner calls out to move, you shift straight to the next column. A steady pace with few corrections produces a tidy graph that reads positively.
- Add two adjacent numbers, write the unit digit, work from bottom to top
- The move signal closes one column and opens a fresh one to the right
- Four aspects are read at once: speed, accuracy, consistency, and endurance
- Kraepelin or koran-test practice sheets filled with columns of single-digit numbers
- A 2B pencil that erases cleanly plus a clean eraser
- A timer or app to mimic the move-column signal every dozen or so seconds
Key Numbers Behind the Kraepelin Test
What the Kraepelin Test Actually Reads
The additions in the Kraepelin test are simple, and that is exactly the point. Because the sums are easy, the assessor can watch how you work without the difficulty of the material getting in the way. What gets measured is your work pattern: how quickly you process, how carefully you keep the results correct, and how long you hold performance once fatigue sets in. The count of numbers you complete in each column is recorded as the column height. When the peaks of all columns are joined into a single line, the resulting graph tells the story of your work rhythm minute by minute. A line that rises then holds high and stable signals a well-kept tempo. A sharply wavering line hints at concentration that slips easily. HR teams and psychologists use this picture to gauge how you might handle work that demands repeated accuracy under deadlines, such as processing data, checking documents, or serving a long queue. Sound preparation gets you used to that pressure pattern well ahead of time.
The Kraepelin and Pauli Tests: Related yet Different
| Aspect | Kraepelin Test | Pauli Test |
|---|---|---|
| Work direction | Bottom to top | Top to bottom |
| Sheet size | Ordinary columned paper | As wide as a newspaper, hence koran test |
| Duration | Dozens of seconds per column, many columns | Around 60 continuous minutes |
| Signal | Move to the next column when told | Draw a line at your last spot when told |
| Scoring focus | Calmness and tempo discipline | Motivation and long-run drive |
Many institutions call both the koran test in general. Ask the organiser or study the opening instructions so you know the work direction being requested.
How to Do the Kraepelin Test Step by Step
These six steps lay out how to do the Kraepelin test, from grasping the instructions to closing the sheet with a graph that reads positively. Rehearse each step on its own first, then combine them in a full simulation.
- 1
Listen to the instructions and set your work direction
Before the start signal, hear the examiner out fully. Make sure you know whether the sheet runs from bottom to top like the Kraepelin test, or top to bottom like the Pauli test. A direction error in the first minute is hard to undo and immediately lowers your result. Study the example the examiner usually shows on the board or the practice sheet. Place your pencil on the first pair of numbers in the requested direction, take a breath, and wait for the official cue. Calmness in those opening seconds carries into the rest of the work.
Tips- Repeat the work direction silently so it does not get flipped under pressure
- Hold the pencil loosely so your hand does not stiffen early

Add two adjacent numbers, write the unit digit
Take two numbers that sit next to each other in a column, add them, then write the result in the small space between them. If the sum is greater than nine, write only the unit digit. For example, seven plus eight is fifteen, so you write only the five. Six plus three is nine, so you write the whole nine. This rule of dropping the tens digit holds throughout the test, so drill it until it becomes automatic. Writing small, clear digits helps you avoid misreading on the next addition. Do not pause to admire a result; move on to the pair above it.
Tips- Drill combinations that make you hesitate, such as eight and nine
- Write digits about half a cell tall so they do not cover the printed numbers
Writing the full two-digit result is the most common slip and it instantly corrupts the next run. - 3
Follow the move signal without looking back
Every time the examiner calls move or line, stop the current column and start the one to its right at once. You simply leave the leftover numbers in the old column, with no regret. Examiners deliberately signal in a quick rhythm, often a dozen or so seconds, to see how you shift focus. Candidates who insist on finishing the old column fall behind and their graph breaks. Treat the signal as a binding beat, and train your ear to respond on the instant. A clean switch keeps the number counts across columns balanced.
Tips- In solo practice, set a timer to beep every 15 seconds to mimic the signal
- The moment you hear move, shift the pencil before overthinking

Keep the tempo steady from column to column
Consistency is worth more than a burst of speed. Many candidates push too hard early, then run out of energy midway so their number counts collapse. A steeply diving graph reads as fragile work stamina. Aim for a roughly equal count in every column, with a modest rise as you warm up. Breathing evenly keeps your heart calm and your hand from shaking. If you feel yourself slowing, tidy the rhythm again instead of forcing a last reserve of strength. A kept tempo yields a high, flat peak line, the picture assessors most favour.
Tips- Learn your comfortable speed through practice; do not copy others
- Avoid glancing at the neighbour's sheet because it splits your focus

Handle mistakes and corrections with a cool head
Miscalculations are inevitable, and your reaction to them is scored too. If you notice an error, cross it out lightly once and write the correct number, without erasing over and over until the paper is a mess. Spending time fixing one old number costs you many new ones. Accuracy is read from how few errors appear across the sheet, so the best move is to protect accuracy from the start instead of patching it later. If a column feels ruined, let it go and give full focus to the next one. A calm attitude after a slip shows the emotional stability the organiser is looking for.
Tips- One light strike-through is enough; skip the time-eating erasing
- Do not panic when you spot an error; carry on so speed does not drop
Getting absorbed in fixing old numbers makes speed fall sharply and the graph look stalled. - 6
Picture the graph shape the assessor wants to read
Each finished column becomes one high point on the final graph. The assessor joins those points into a curve and draws a reference line to judge your consistency. The ideal picture is a curve that rises early, then holds high and smooth to the end, with few errors. Such a curve speaks of someone who adapts quickly, stays stable, and resists fatigue. This knowledge changes how you spend your energy: you stop chasing one giant column while leaving another empty. You spread the effort so each point stands level and the final line flows calmly.
Tips- After practice, join your own column peaks to see your pattern
- Work on the lowest column in your next practice session
Four Aspects Scored at Once
Work Speed
Counted from the number of correct additions within the available time. The more accurate numbers, the higher the work tempo shown.
Work Accuracy
Read from how few errors appear across the sheet. Kept accuracy shows the carefulness that repetitive work demands.
Work Consistency
Judges how stable the number count stays from column to column. Small differences in column height signal controlled focus and emotion.
Work Endurance
Seen in the ability to hold performance to the final column. A line that stays high at the close shows stamina.
“What decides the koran test is a kept rhythm that outweighs any fleeting top speed. Candidates who spend a few weeks practising a stable tempo almost always produce a tidier graph than those who rely on raw energy on test day.”
Physical and Mental Prep for Test Day
- Sleep well the night before so focus and eyes stay fresh
- Eat a light breakfast so energy lasts to the final column
- Arrive early to ease nerves and settle into the room
- Bring a spare 2B pencil and a clean eraser
- Practise short belly breathing to lower your heart rate while waiting for the signal
- Do at least one full simulation the day before so your hand is already warm
