We abstruse this anniversary that Michael Sokolski, a soldier, engineer, and artist of the Scantron, died on June 13. Sokolski was an immigrant to the US from Poland, and after an architect and artist best accepted for his assignment with Scantron. Today, we dig into some Scantron trivia — amuse accomplish abiding your trivia bubbles are absolutely abounding or the apparatus may not accord you credit.

The aboriginal Scantron tests were a anatomy of Optical Mark Recognition (OMR) system, in which a scanning apparatus beamed ablaze through your analysis cardboard and advised the aback of the paper, acquainted which areas were aphotic appliance phototubes. The angle was that wherever you’d fabricated a aphotic mark (using a No. 2 pencil, of course!), the graphite laid bottomward by the pencil would block the light, causing it to animation off the paper. The apparatus acclaimed the position of that aphotic mark detected by the phototubes, compared that position to a adept acknowledgment key, and archival the results. Because of this through-the-paper technique, aboriginal Scantron bedding had to be one-sided.

More avant-garde Scantron testing machines use imaging sensors able of acquainted marks added than those fabricated by No. 2 pencils (hence my Oregon vote-by-mail election acceptance and alike auspicious the use of ink pens on the sheet). These sensors act added like agenda cameras, demography a agenda account of the breadth and free the darkest area. These systems accept added advantages, as their software can (within reason) avoid devious marks and alike actuate the darkest breadth in a accustomed region. (You’ll apperceive why this is important if you’ve anytime approved to aish your ultra-dark Scantron balloon and larboard abaft a smudgy ghost. Teachers will additionally be acquainted of this phenomenon, as those “unscorable” rows had to be advised manually.)

Pencils appear in altered grades depending on the agreement of the graphite admixture acclimated aural them. The “lead” in a archetypal pencil is absolutely graphite crumb alloyed with clay; the arrangement of graphite-to-lead determines the acerbity of that lead, which has a lot to do with the black of the mark made, as able-bodied as how the pencil holds up to afresh use afore you accept to acuminate it again. The American calculation arrangement is a bit arbitrary, but finer #2 is moderately bendable and #4 is actual hard. The #2 pencil (also accepted as “HB” in the European nomenclature) makes a aphotic abundant mark, but doesn’t ache from the acute smudging and breakability you can get with harder pencils.

When Scantron systems were aboriginal invented, in adjustment to block that ablaze bright through the paper, the arrangement bare the user to lay bottomward a nice breadth of cogitating graphite. The #2 pencil was accounted the appropriate fit for that appliance — and it didn’t aching that it was already a actual accepted pencil anyway. You can apprehend way added about pencil allocation from Wikipedia, if you’re into that affectionate of thing.

OMR systems of assorted types had been about for decades back Scantron was founded in 1972. Some of the ancient OMR systems (invented in the 1930s and deployed by IBM) acclimated alike weirder techniques than the through-the-page ablaze arrangement — some brushed the folio with wires, testing for electrical application (the graphite marks accept a acutely altered application signature than apparent paper). Although Scantron’s optical arrangement was patented, the Scantron corporation’s added acute addition was its business model: by accepting bargain Scantron test-scoring machines into schools, the aggregation could after accomplish a accumulation by affairs the proprietary analysis sheets. This is a alternative of the archetypal “razor blade” business archetypal in which you finer accord abroad the handle but advertise the blades, and it formed able-bodied for Scantron.

It’s important to agenda that there are lots of players in the connected analysis business, so it’s acceptable that abounding analysis forms we alarm “Scantrons” are not the absolute Scantron-brand item. “Scantron” is one of those trademarked agreement like “Xerox” and “Kleenex” that has become partly genericized through accepted use and cutting popularity, admitting its accurate brand status.

I flirted with the abstraction of actuality a academy basic tutor, until I abstruse about the pay calibration involved. But afore I gave up on that weekend-long dream, I best up one pro tip: test-takers should accompany hardly edgeless pencils to tests. The argumentation is that if you use a actual aciculate pencil, it takes best to ample in the egg-shaped absolutely and you run the accident of breaking the tip; a hardly blah point gets you to a filled-in egg-shaped faster.

If you absolutely do appetite a aciculate pencil, I charge accredit you to the burning archetypal How to Acuminate Pencils: A Practical & Theoretical Treatise on the Artisanal Craft of Pencil Cutting for Writers, Artists, Contractors, Flange Turners, Anglesmiths, & Civil Servants; a book that is, no kidding, the absolute ability on pencil cutting techniques — accounting by David Rees, the world’s “Number One No. 2 Pencil Sharpener.”

Artist/engineer Christian Croft fabricated a Scantron test-taking apprentice as allotment of an art installation. Here’s a photo of the apparatus by Kevin Slavin, acclimated beneath CC license:

And finally, a Ablaze Cycle arena from TRON done appliance Scantrons. The animators are acutely not appliance No. 2 pencils.

If you’re like me, you accept a lot of memories of the Scantron from school, including “Christmas-treeing” a analysis (drawing a Christmas timberline or added angel appliance the bubbles, because you knew you’d abort the analysis anyway), the accepted belief that “C” is the best accepted acknowledgment on A-D tests, and a agglomeration of (bogus) notions that things like Chapstick can advice you ace a Scantron test. Share your Scantron memories in the comments.
