Abstract
Implementations feature scannable form techniques and systems. Some aspects feature a scannable form including at least one response column parallel to a first longitudinal edge of the scannable form, and a broken ladder having two substantially parallel lines with locations for multiple rungs corresponding to encoded information that identifies a person assigned to the scannable form. A top rung is positioned on the scannable form so that the top rung can be a first rung that is scanned by a test scoring machine for the broken ladder, and a bottom rung is positioned so that the bottom rung can be a last rung that is scanned by the test scoring machine for the broken ladder. Other aspects feature a method to determine correct scoring key data in the test scoring machine for a test, and a method of transmitting information between the test scoring machine and a portable memory device.
