Patented Scoring, Automatic Data Capturing and Tabulation Technology
ACCURATE TEST GRADING, SURVEY FORM DATA COLLECTION AND DATA CAPTURING SYSTEM AND CENSUS TABULATION SOLUTIONS
Traditional small scale tests, assessments, exams, surveys and census questionnaires are scored manually. It’s too expensive to generate and print special “forms” that can be recognized by commercial optical scanners. When large scale surveys and tests are undertaken, forms are designed to fit special Optical Mark Recognition (OMR) requiring specific columns across a special form of paper. These paper tests or surveys must use a commercial printer at high expense. The OMR scanners are specialized and can only tally the forms with a custom program used to generate the questionnaire form.
The picture below is a screen shot of a digital image of a ballot to demonstrate how the AVANTE system tallys elections. Similar technology can be used for scoring tests. The captured digital images of tests allow for more freely distributed essay type questions for easier grading. Distribution of digital test images also allows for easier peer review of previously scored exams.
When doing surveys, digital images may be posted for public review enhancing public confidence.
Below is a typical commercial-off-the-shelf cost effective document scanner for use in even the largest of public tests, assessments, surveys and polls tabulation solutions. A properly configured system with 10 of these units could tabulate over 1,000,000 double-sided tests or survey forms in less than 24 hours.

AUTOMATIC ACCURATE DATA CAPTURING AND TABULATION OF ANSWERS FOR TEST GRADING & SURVEY DATA CAPTURING WITH STANDARDIZED OR CUSTOMIZED TEST FORMS, SURVEY DATA COLLECTION FORMS AND CENSUS QUESTIONNAIRES
(US 6,892,944; 7,077,313; 7,614,553 and other AVANTE pending patents incorporating imaging, scaling and pixel counting optical scan solutions)
AVANTE couples the accurate data capturing technology from test and survey forms and questionnaires for use as an accurate test grading solution and assessment tabulation system. These data collection and data capturing software solutions incorporate a flexible form generation software and solution to provide the most advanced e-TEST and e-SURVEY systems since the first use of OMR technologies. The patented scaling of paper shrinkage or expansion and the quantitative pixel counting enable direct and automatic accurate data capturing of addresses, names and other demographic data that may otherwise require keying in manually. The total automatic data capturing, deciphering and tabulation of survey and census form information dramatically reduces costs in large scale survey applications such as a national census.
The 2006 SAT test scoring and grading errors by the tabulation company engaged by the College Board highlights the need for upgrading current scanning technology. The test assessment and grading errors were attributed to moisture induced paper expansion and the inability to resolve lightly marked “bubble marks”.
The inability to resolve lightly marked “bubble marks” and errors due to paper expansion or shrinkage is a chronic industry problem. Combined with paper alignment errors, approximately 1.5% of the SAT tests were tallied incorrectly. The largest scoring and grading error rate was 450 points or 19% on a test of 2400 points or 25% for a 1600 point test.
Mostly unknown to the public, similar grading and assessment error rates appear in tallies of votes in US elections when paper ballots are used. The Federal Voting System Standards of 2002 specifically mandates voting systems to have less than 1 error in 1.5 million marks when the paper ballot is marked correctly (i.e. properly filled “bubble marks”). Systems using discrete sensor/OMR technology struggle to meet such requirements.
AVANTE International Technology’s test and survey scoring solution spins off from its EAC certified system for tallying voting ballots using pixel count and document imaging technology. AVANTE Optical VOTE-TRAKKER™ was the first to pass and exceed federal testing with 0 errors in 1,500,000 marks. The same technology can be used for scoring tests, tabulating surveys and questionnaires.
The discrete Optical Mark Recognition (OMR) sensor technology relies on completed documents passing through the scanner “exactly” straight. The width marking positions must line up “correctly” and timing must be exact for reading the length of the paper. With the use of advanced document imaging technology, AVANTE uses fiducial markings to scale for paper orientation and expansion/shrinkage variations. The quantitative use of counting pixels in each “bubble mark” also provides automatic self-checking for possible light marks, smears or errors. The following table is a summary of the differences between traditional discrete sensor OMRs and AVANTE’s imaging with quantitative pixel counting technology.
