How accurate are scantron machines?
The Scantron 888P+ model can grade as many as 40 tests per minute with a 99.9% accuracy rate. Scantron forms contain an infrared light-reflecting ink. When a form passes under an internal read head, the machine notes where the light has been absorbed by pencil lead.
What happens if you use a pen on a scantron?
Modern scantron systems are quite high-tech, using image sensors and sophisticated image processing algorithms. As such, you can use pens, pencils, and even printer toner or ink, if you want to run your scantron through a printer to mark all your answers.
How does a scantron work?
How does Scantron work? Scantron is a multiple-choice test tool that is available to faculty and staff in the Faculty of Arts. It offers specialized forms which are filled in by students during their exam and then fed through a specialized Scantron scanning machine to automatically score, analyze and print data.
How long does a scantron take?
Each test will take approximately one hour.
Do teachers still use scantrons?
He said most teachers have generally stopped using scantrons, but are starting to turn to a new method of test assessment. “Most of the teachers don’t use scantron machines anymore. A lot of them are using Mastery Manager now and are using that system vs. scantrons,” Shaughnessy said.
Why do schools require number 2 pencils?
According to Dictionary.com, early machines that scanned and recorded test scores couldn’t properly detect marks made by hard pencils. While No. 1 — the softest — pencils were prone to smudging, the No. 2 pencil was the perfect balance of softness and hardness.
Is Scantron still used?
Do Scantrons read pen?
The pencil lead weight that corresponds to #2 pencil lead is “HB.” With the same type of lead, it’s deeply unlikely any scantron machine in use today, no matter how outdated, would have trouble reading your markings. (You can read more about lead grades and mechanical pencils here if you are interested.)
How many questions are on the Scantron test?
There is no set number of questions. The average number of questions in a testing session is about 50.
How much are scantrons in college?
You can buy an 882-E Scantron Answer sheet, 100Q, for about $76 per 500 packages. It costs around $0.15 per sheet! That means you can still sell them to your fellow students at a reasonably lower price than they can find anywhere and still make an easy profit.
What is Abracadabra?
ABRACADABRA ( A B roadband/ R esonant A pproach to C osmic A xion D etection with an A mplifying B -field R ing A pparatus) is a new search for axion dark matter. If they exist, axions modify Maxwell’s equations, and ABRACADABRA (or ABRA for short) exploits this by using a toroidal magnet to source an effective electric current.
How does the abracadabra-10cm work?
This effective current then induces an oscillating magnetic flux through the center of the toroid, which is detected and amplified with a pickup loop and SQUID magnetometer. The current generation, ABRACADABRA-10cm, is located at MIT.
What is Scantron?

What happens if you draw on the black lines on Scantron?
If you draw on the black lines on the sides of your Scantron, you might fail the test. Scantrons that can’t go through the machine usually aren’t graded. Some people also try writing on the black lines and then erasing them, which has the same effect.
