OMR software offers speedy solutions for reading scanned OMR sheets. Note that actual application of the software solution comes only at a later stage. The OMR sheets collected from the candidates need to be scanned using any regular ADF scanner as the first step of the evaluation process. The scanned images are then read by the OMR software to collect and correlate the data and obtain statistical reports.
The time taken to scan the OMR sheets depends on the type of scanner you use and the number of sheets to be scanned. A flatbed scanner will obviously take a longer time as you can only scan one document at a time, and hence is not advisable for larger projects involving thousands of sheets. For projects involving such magnitude of sheets, automatic document feeders or ADF scanners are preferred, scanning speeds of which range from 10 sheets/min to over 100 sheets/min. For a fairly sized educational institution or an IT service provider taking up projects of evaluating 3000-4000 candidates, ADF scanners with scanning speed of about 30-40 sheets/min should suffice.
The standard OMR software versions can accurately read up to hundred sheets in two minutes. The software can read a sheet per second on an average PC. Note that the OMR software speed remains undeterred by the total number of sheets to be scanned, and using the software on heavily configured PC will deliver consistent high reading speeds of over 3 sheets per second.
Advanced versions of the OMR software come with customizations that facilitate reading at very high speeds (up to 10000 sheets per hour in the auto mode). Reading in the auto mode means the software does not re-read the sheets or prompt for user checks whenever there are abnormalities in the verification process. It instead rejects the doubtful reads and moves onto the next sheet. Rejection can be prevented by using the manual mode, but auto mode is usually preferred for it enables sheet reading at maximum speeds.
Users sometimes experience rejection issues due to simple mistakes made by the candidates while filling the sheets, such as left out Roll no. fields or incorrectly filled Roll numbers, multiple answers selected, half-filled bubbles etc. Such skipped reads can be selected and run through the alert mode, where the users can conveniently attend to rejected issues by manual mode of instructions. It is hard to comment on the speed of rejection checks, for resolution of these issues calls for human responses, which cannot be generalized.
Once the sheets are properly read and all rejected issues fixed (excluding a select few that cannot be fixed, like blank OMR sheets etc), the collected data is encrypted and uploaded onto a central server location for speedy generation of reports and results. The OMR software speed of merit list generation separately according to the topics, sections, class etc, does not involve additional time, and the processed data is readily available for representation by means of various modes, such as rank lists, graphs, charts etc. Any specific alterations needed in the output can be done after exporting the results into Excel files.
