Perfect-content-validity objective tests

A method of non-sampling process for producing perfect-content-validity tests by:

• Step 1:
• Preparing a list of all--more than three--fragments, or nanoskills, of human behavior, experience, and knowledge which exit in the entire subject-matter area to be tested,
• Step 2:
• Arranging the listed nanoskills in developmental, logical, or psychological sequence,
• Step 3:
• Designing a preliminary test item for each sequenced nanoskill whose application can lead to the correct answer to the item,
• Step 4:
• Labeling the first preliminary test item in the sequence with “N” and checking the second item whether it requires the application of the nanoskill demanded in the first item:
• A. If yes, labeling this item with “Y” or
• B. If no, labeling this item with “N”,
• Step 5:
• Checking whether the third preliminary test item requires the applications of the nanoskills demanded in the previous two items:
• A. If yes, labeling this item with “Y” or
• B. If no, labeling this item with “N”,
• Step 6:
• Checking the labels assigned to the second and the third items in the sequence:
• A. If “YY”, “NN” or “NY”, going to Step 7, or
• B. If “YN”, earmarking the Y-label item with “C” before going to Step 7,
• Step 7:
• Checking whether the next preliminary test item along the sequence requires the application of the nanoskill demanded in the previous item:
• A. If yes, labeling this item with “Y” or
• B. If no, labeling this item with “N”,
• Step 8:
• Checking the two labels most recently assigned:
• A. If “YY” or “NY” which belong to the last two items in the sequence, earmarking “C” by the last Y-label item and going to Step 9,
• B. If “NN” which belong to the last two items in the sequence,
• earmarking “C” by these two items and by other N-label items preceding these two up to the last Y-label item, if any, and going to Step 9,
• C. If “YN” which belong to the last two items in the sequence,
• earmarking “C” by each of these two items and going to Step 9,
• D. If “YY”, “NN”, or “NY” which do not belong to the last two items in the sequence, going back to Step 7, or
• E. If “YN” which do not belong to the last two items in the sequence,
• earmarking “C” by the Y-label item and going back to Step 7, and
• Step 9:
• Collecting all items earmarked “C” as final test items to produce a perfect-content-validity test.
