Avoid the unnecessary repetition of a word at the beginning of each option. Therefore the maximum number of content should be incorporated in the material of the item.

 Take care that the content or approach to item not offended, principle or in fact, the student in terms of its culture, its social and economic level creed religious or political; their ethnic group and that does not serve to reinforce racial and gender discrimination.

 Use positive wording, i.e. non terms of significance negative, especially when its use affects the clarity of the required task or hinders comprehension quick and accurate item.

 Use questions based on the item where possible. These questions must be direct, simple, exposed very clearly and it must of course be question marks. This is another way of writing the foot of the selection item.

 Language standards of punctuation and grammatical concordance. You must specify therefore very well the appearance you wish to raise, so keep logic and cohesion. On the base in question form options start with uppercase; When options correspond to aspects enumerations, two points at the end of the base are placed and if it's options that contain a single feature, any punctuation mark is placed at the end of the base.

Aspects identified in the previous lines referred to General characteristics of the foot or contained in a single selection item. In connection with the detractors and key requirements should be met as mentioned Thyne (1978):

The word distracting assigns PEAR differentiate options implemented for ill-prepared students key or ignore the contents of the item or lack of knowledge. I.e., that this name designates options which distract those who don't know or that are incorrect according to what raises the base. Quoted by Hernandez, in Thyne (1978), describes precisely the role of a distracting is "prevent that they receive the answer as a gift to exclude the possibility of answering correctly in spite of their ignorance" (quoted by Hernandez, p. 311).

In item selection, the detractors should be fully attractive as advised the writings of matter, to achieve a high level of discrimination. It is essential, therefore, are logical and meaningful not only themselves, but with the essence of the content expressed on the basis of the item. These conditions only are achieved when the detractors are not easy to answer using common sense or logic is necessary prevent fact students screen choices by obvious.

The correct answer must meet the requirement of precision and accuracy. Key or selection, item response requires students to capture or recognize the substance contained in the material or base. Select the correct option indicates an objective, content or a given knowledge domain.

In this type of sub-menu item if the student hits the response, it can be concluded that it has been able to extract the essence of the statement, act according to the signal given in the body of the item and, therefore, deduce the key.
