Structure and Sequence:

The course is divided into 47 modules. Some modules may be divided into a number of instructional modules that may include both a "Core" and "Specific" sections. A Core section covers the general aspects that apply to both the inch and metric measurement system. Each Specific section explains how a particular task is accomplished using either the Inch or Metric system.

After watching the Core and Specific instruction, you answer the printed Work Sheet questions to be sure that you have acquired all the information. Then the Interactive Test for each Module can be completed. Once all the test questions are 100% correct, you can begin the next module.

Modules and Sections:

There are a total of 644 questions in the tests if all 47 modules are included, but some of those questions may have as many as 20 steps that must be completed. These multi-step questions are typically "simulation " questions that require you to complete a measurement task. Remember, you cannot fail these tests! If you make a mistake, simply go back to the instruction to figure out what you did wrong, then try the question again. The goal of this course is to make sure you have the information that you need to perform the job tasks.

If you select the Inch system, you will answer 575 questions as you progress. If Metric is selected, you receive 574 questions. If both systems of measurement are selected, you receive all 644 questions. Since some of these question have multiple steps, you are effectively answering approximately 800 questions.

Module Flow:

As you begin a module, you will see the Core section of instruction. Next, assuming you were signed up for the Metric measurement system, you would see the instruction for that specific measurement system if one is available for that module.

The Work Sheet, generated and printed from the web pages, would include questions covering both the Core and Metric specific instruction. As you attempt to answer the questions, you can return to look at either the Core or Specific instruction as many times as you need. Taking the time to answer all the Work Sheet questions will make it much easier for you to answer the Interactive test that follows.

Once you complete the Work Sheet, you can proceed to the Interactive Test. The test may have all of the Core questions followed by all the Specific questions, or it may have the Specific questions interspersed within the Core material. The order the questions are presented will follow the sequence used in the instructional material.

Job Aids:

In addition to the instruction and Work Sheets, job aids are available. The 40 page "Geometric Dimensioning and Tolerancing Job Aid" is a PDF file that should be printed. It provides a detailed explanation of the various symbols and provides a graphic illustration of the correct method of performing the measurement on a surface plate. - Sample Job Aid
