Study notes
The STEP (Skills Toward Employment and Productivity) Skills Measurement program is the first ever initiative to generate internationally comparable data on skills available in developing countries. The program implements standardized surveys to gather information on the supply and distribution of skills and the demand for skills in labor market of low-income countries.
The uniquely designed modules in the Employer survey aim to assess the structure of the labor force; the skills (cognitive skills, behavior and personality traits, and job-relevant skills) currently being used; the skills that employers look for when hiring new workers; the propensity of firms to provide training (including satisfaction with education, training, and levels of specific skills) and the link between skills and compensation and promotion. The survey also captures background characteristics (size, legal form, industry, full time vs. non-standard employment, occupational breakdown), performance (revenues, wages and other costs, profits, scope of market), key labor market challenges and their ranking relative to other challenges, and job skill requirements of the firms being interviewed. An additional component of the survey conducted in Vietnam is a module on innovation designed to capture the characteristics of Research & Development (including factors related to product development and capacity building).
The questionnaire can be adapted to address a sample of firms in both informal and formal sectors, with varying sizes and industry classifications.

Sampling
Sampling procedure
The sampling objective of the survey was to obtain interviews from 400 non-government enterprise workplaces in the capital and urban regions of Vietnam.
Two-stage stratified random sampling was used in the survey. A list of businesses registered with the General Statistics Office Vietnam enterprise census 2009 served as the sampling frame for formal sector. Informal sector firms were drawn from a sample created using data from the Departments of Planning and Investment (DPIs).
Detailed information about the sampling is available in the Vietnam Survey Implementation and Findings Report and Vietnam Employer Survey Weighting Procedure, provided as an external resource.

Response rate
An overall response rate of 63.8% was achieved in Vietnam STEP Survey. Detailed distribution of responses by stratum can be found in the Vietnam Employer Survey Weighting Procedure (Table 6), available as an external resource.
Weighting
The Vietnam Employer Survey data was weighted in order to correct for imperfections in the sample that might lead to bias between the sample and the target population. Such imperfections include the selection of firms with unequal probabilities between strata, sample frame imperfections such as ineligible and duplicate firm listings, and non-response. In other words, the purposes of weighting are:
1) To compensate for unequal probabilities of selection between strata;
2) To adjust the target population size for ineligible and duplicate firm listings;
3) To compensate for non-responding firms.
The weights were constructed as follows:
1) A Theoretical Design Weight, TheorWtStr, was calculated for each of the 594 sampled firms. This is a stratum weight based on the stratified sample design. Each sampled firm’s Theoretical Design weight is the number of firms that each sampled firm represents in the sample frame. This weight is the inverse of the probability of selection in a stratum.
2) The sample frame stratum population counts, PopnStr, were adjusted to take into account the number of ineligible firms in each stratum sample. The resulting adjusted stratum population size is the variable‘PopnStrAdj’.
3) A final population stratum weight, PopnWtFin, was constructed by adjusting the Theoretical Design Weight,TheorWtStr for:
a. Number of ineligible firms in the sample
b. Number of non-responding firms in the sample

Mode of data collection
Face-to-face [f2f]
Data collection supervision
The data collection team consisted of a total of 11 interviewers and 2 Survey Managers. Each interviewer reported to a Survey Manager.
Survey Managers’ responsibilities include:
- Coordinating fieldwork in the assigned region
- On-going monitoring of interviewers’ work
- Checking non-response, activation of reserves, problems encountered, and communicating regularly with the Headquarters
- Submitting questionnaires and fieldwork tracking forms to Headquarters
For quality control, Survey Managers were responsible for:
- Check each accepted questionnaire for completeness and accuracy before submitting to Headquarters

Questionnaires
The Questionnaire for the Vietnam STEP Employer Survey consists of six modules:
Section 1 – Work Force
Section 2 – Skills Used
Section 3 – Hiring Practices
Section 4 – Training and Compensation

Data Processing
Data editing
STEP Data Management Process:
1) Raw data is sent by the survey firm.
2) The World Bank (WB) STEP team runs data checks on the Questionnaire data. Comments and questions are sent back to the survey firm.
3) The survey firm reviews comments and questions. When a data entry error is identified, the survey firm corrects the data.
4) The WB STEP team again check to make sure the data files are clean. This might require additional iterations with the survey firm.
5) Once the data has been checked and cleaned, the WB STEP team computes the weights. Weights are computed by the STEP team to ensure consistency across sampling methodologies.

Data entry processes, including team composition are described in the Vietnam Survey Implementation and Findings Report available as an external resource. In most countries, data entry took place at the survey firm's headquarters.
Questionnaire Data:
- For the Questionnaire data, survey firms could use the World Bank STEP Data Entry Program (DEP) or design their own. In the latter case, the WB STEP team checked their DEP to ensure it complied with STEP Technical Standards. The STEP DEP was developed in Excel and mirrored the Questionnaire. Vietnam developed their own DEP on Excel.
Double data entry process was required. All range checks and skips were controlled by the program. Consistency checks were also included in the data entry program.
