Writing a Questionnaire

My organization is a child care center for ages 3 to 7 year olds. This organization is a teaching organization for the children as well as daily child care. My childcare center will have certified teachers for half the day. I want to create a questionnaire to go with my paper. I hope you can assist with the questionnaire. It should have the following items in the questions (please indicate any in-text citations and references for me to follow along):

1.) Developed a 15-item questionnaire to capture employee engagement in an organization.

2.) Ensure that the questions are operationalized.

3.) Ensure the survey questionnaire addresses the following:

a). Capture the essence of employee engagement in a particular organization
b). Measure what it intends to measure
c).Provide similar results over time when administered subsequently in the same organization or in different organizations
