About the Reasoning from Rules section
Reasoning from Rules is one of the four tests in EEI's TECH battery. EEI's brochure says it measures the ability to read and apply rules to make decisions and to troubleshoot a logic network. As with two other TECH tests, it publishes no question count and no time limit.
Our rule sheets are original and set in technician work: a chemistry lab's sample intake, relay test scheduling, drawing change requests, work order priorities, telecom tickets, a meter shop, purchasing, fleet, calibration, spill reporting, GIS edits, estimating and a test-equipment store. Every rule is invented for practice. Questions ask what happens to a case, which rule decides it, which of several cases gets a given outcome, and which single change would flip the outcome — the last two are where rule order catches people out.
The logic networks are small: switches drive AND, OR, NOT and ONE boxes that light a lamp. You work out what is on, which switch would change the lamp, and — from readings taken at every box — which box has failed. Every key is decided by evaluating the rules or the network, and a separate checking script decides each one again.
Tips from practice
- Go down the sheet in order and stop at the first rule that fits. A later rule that also fits does not count.
- Check every condition in a rule. "Over 48 hours" does not include 48; "48 hours or more" does.
- Answer from the sheet, not from what you would do at work. The rules are the whole world of the question.
- To find a failed box, check each one against its rule using the inputs it is actually getting, including other boxes' readings.
Common questions
- What is a logic network on the TECH test?
- EEI's brochure says only that the test includes troubleshooting a logic network. Ours uses boxes with simple stated rules — AND, OR, NOT and ONE — so everything you need is on the page. No electronics knowledge is assumed.
- Are these real procedures?
- No. Every rule sheet is invented for practice and says so. The skill being practiced is applying written rules exactly, not learning any company's procedure.
