The standard MICS4 questionnaires have been adapted to include several country-specific modules as well as all the standard questions from the questionnaire modules. Three sets of questionnaires were used in the survey:

1) A household questionnaire which was used to collect information on all de jure household members (usual residents), the household, and the dwelling.
2) A women's questionnaire administered in each household to all women aged 15-49 years; and
3) An under-5 questionnaire, administered to mothers or caretakers for all children under 5 living in the household.

The household questionnaire included the following modules:
- Household Listing Form
- Education
- Water and Sanitation
- Household Characteristics
- Child Labour
- De-worming (Nepal Specific Module)
- Child Discipline
- Handwashing
- Salt Iodization

The Questionnaire for Individual Women was administered to all women aged 15-49 years living in the households, and included the following modules:
- Women's Background
- Access to Mass Media and Use of Information Communication Technology
- Desire for Last Birth
- Maternal and Newborn Health
- Illness Symptoms
- Contraception
- Unmet Need
- Attitudes towards Domestic Violence
- Marriage/Union
- HIV/AIDS
- Tobacco and Alcohol Use
- Life Satisfaction

The Questionnaire for Children under five was administered to mothers or caretakers of children under 5 years of age living in the households. Normally, the questionnaire was administered to mothers of under-5 children; in cases when the mother was not listed in the household roster, a primary caretaker for the child was identified and interviewed. The questionnaire included the following modules:
- Age
- Birth Registration
- Early Childhood Development
- Breastfeeding
- Care of Illness
- Malaria
- Immunization
- Child Grant (Nepal Specific Module)

The questionnaires are based on the MICS4 model questionnaire. From the MICS4 model English version, the questionnaires were translated into Nepali and two other local dialects, Tharu and Awadhi, which are spoken in the Terai region and were pre-tested in Jumla (Mountain/Rural), Salyan (Hill/Rural) and Banke (Terai/Urban) during July 2010. Based on the results of the pre-test, modifications were made to the wording and translation of the questionnaires. However, due to sensitivity of language issues in present transitional political context of the country and implication on other surveys to be conducted by CBS, Nepali questionnaire was used to record the data.

In addition to the administration of questionnaires, fieldwork teams tested the salt used for cooking in the households for iodine content and observed the place for handwashing. Details and findings of these measurements are provided in the respective sections of the report.
