Face-to-face [f2f]
The survey training was conducted by the Survey Technical Team, the National Bureau of Statistics, National Population Council, and the Federal Ministry of Health with support from eHealth Africa.
Galaxy tab 4 7.0" were used to collect data in the field. Collected data were automatically sent to a central server using 3G internet connection using FormHub (Open Data Kit) and immediately analysed for key quality checks. Results displayed on a purpose built dashboard and analysis with STATA served as the basis for communication between the coordinator and the rest of the survey teams during entire data collection period.

The trainings started on the 22nd of June 2015 and conducted in three rounds of 5 days each. Each training had a maximum number of 36 participants. It has been found that limiting the number of
participants greatly increases quality of trainings in Nigeria

Prior to the start of the data collection phase, the selected local government area (LGA) authorities were informed about the survey in order to facilitate the informing of community members about data collection and gain support from the officials and the community. Each team had its own vehicle and was accompanied by a driver. To minimise travel times, teams were advised to stay in the nearest LGA.
Survey teams started fieldwork in the same location where training was conducted in order to make supervision of all teams by senior survey staff possible.
The National Bureau of Statistics (NBS), the National Population Commission (NPopC), Federal Ministry of Health (FMOH) and UNICEF selected 121 persons to be involved in the survey. Of the 121 individuals, 112 constituted the survey teams and 9 individuals were assigned as standby to replace any interviewers who dropped out during the data collection period. Of the 112 individuals, 90 of them were assigned to 30 survey teams (3 individuals per team, of which 1 team leader and 2 measurers), 10 supervisors, 1 national coordinator, 1 assistant national coordinator, 3 training coordinators, 2 technical coordinators and 5 regional coordinators.

To ensure the quality of data, supportive supervision was provided for the teams at different level. The first level of supervision was provided by the team supervisors who were responsible for closely monitoring the work of the teams to ensure that all sampled households were visited and eligible children and women included. An important element of these supervisors was to facilitatelogistics, organize the team movement within the state, reviewing listing of households, systematic selectin of households and supporting in measurement and age estimation The main aim of such support was needed to uncover any deliberate distortion of household listing and selection of households, age estimation or omission of household members by interviewers so as to reduce their workload. Supervisors also observed the interview to ensure that the survey team were conducting the interviews as per the interview manual.

The second level of supervision consisted of regional coordinators and state level government officers visit to the field and regularly check teams on their work. Strengths and weaknesses were discussed in review session with the teams.
