Southern and Eastern Africa Consortium for Monitoring Educational Quality 2000
Zanzibar SACMEQ II Project
In 1991 the International Institute for Educational Planning (IIEP) and a number of Ministries of Education in Southern and Eastern Africa began to work together in order to address training and research needs in Education. The focus for this work was on establishing long-term strategies for building the capacity of educational planners to monitor and evaluate the quality of their basic education systems. The first two educational policy research projects undertaken by SACMEQ (widely known as "SACMEQ I" and "SACMEQ II") were designed to provide detailed information that could be used to guide planning decisions aimed at improving the quality of education in primary school systems.
During 1995-1998 seven Ministries of Education participated in the SACMEQ I Project. The SACMEQ II Project commenced in 1998 and the surveys of schools, involving 14 Ministries of Education, took place between 2000 and 2004. The survey was undertaken in schools in Botswana, Kenya, Lesotho, Malawi, Mauritius, Mozambique, Namibia, Seychelles, South Africa, Swaziland, Tanzania, Uganda, Zambia and Zanzibar.
Moving from the SACMEQ I Project (covering around 1100 schools and 20,000 pupils) to the SACMEQ II Project (covering around 2500 schools and 45,000 pupils) resulted in a major increase in the scale and complexity of SACMEQ's research and training programmes.
SACMEQ's mission is to:
a) Expand opportunities for educational planners to gain the technical skills required to monitor and evaluate the quality of their education systems; and
b) Generate information that can be used by decision-makers to plan and improve the quality of education.

The survey covered only Zanziba.
Unit of Analysis
The target population for SACMEQ's Initial Project was defined as "all pupils at the Grade 6 level in 1995 who were attending registered government or non-government schools". Grade 6 was chosen because it was the grade level where the basics of reading literacy were expected to have been acquired.

The sample designs used in the SACMEQ II Project were selected so as to meet the standards set down by the International Association for the Evaluation of Educational Achievement. These standards required that sample estimates of important pupil population parameters should have sampling accuracy that was at least equivalent to a simple random sample of 400 pupils (thereby guaranteeing 95 percent confidence limits for sample means of plus or minus one tenth of a pupil standard deviation unit).
Some Constraints on Sample Design
Sample designs in the field of education are usually prepared amid a network of competing constraints. These designs need to adhere to established survey sampling theory and, at the same time, give due recognition to the financial, administrative, and socio-political settings in which they are to be applied. The "best" sample design for a particular project is one that provides levels of sampling accuracy that are acceptable in terms of the main aims of the project, while simultaneously limiting cost, logistic, and procedural demands to manageable levels. The major constraints that were established prior to the preparation of the sample designs for the SACMEQ II Project have been listed below.
Target Population: The target population definitions should focus on Grade 6 pupils attending registered mainstream government or non-government schools. In addition, the defined target population should be constructed by excluding no more than 5 percent of pupils from the desired target population.
Bias Control: The sampling should conform to the accepted rules of scientific probability sampling. That is, the members of the defined target population should have a known and non-zero probability of selection into the sample so that any potential for bias in sample estimates due to variations from "epsem sampling" (equal probability of selection method) may be addressed through the use of appropriate sampling weights (Kish, 1965).
Sampling Errors: The sample estimates for the main criterion variables should conform to the sampling accuracy requirements set down by the International Association for the Evaluation of Educational Achievement (Ross, 1991). That is, the standard error of sampling for the pupil tests should be of a magnitude that is equal to, or smaller than, what would be achieved by employing a simple random sample of 400 pupils (Ross, 1985).
Response Rates: Each SACMEQ country should aim to achieve an overall response rate for pupils of 80 percent. This figure was based on the wish to achieve or exceed a response rate of 90 percent for schools and a response rate of 90 percent for pupils within schools.
Administrative and Financial Costs: The number of schools selected in each country should recognize limitations in the administrative and financial resources available for data collection.
Other Constraints: The number of pupils selected to participate in the data collection in each selected school should be set at a level that will maximize validity of the within-school data collection for the pupil reading and mathematics tests.
The Specification of the Target Population
For Zanzibar, the desired target population was "all pupils enrolled in Standard 6 in the ninth month of the school year (i.e., in September 2000)". The net enrolment ratio in Zanzibar in 2001 was 76.0. However, it was decided to exclude certain pupils. These were pupils in schools having fewer than 20 Standard 6 pupils in them and pupils in special schools. In all 138 pupils from 10 schools were excluded but this only amounted to 0.6 percent of all pupils. In Zanzibar there were 161 schools having 22,179 pupils in 2000. After excluding the 0.6 percent of pupils, the defined population from which a sample had to be drawn consisted of 22,041 pupils from 151 schools.
Note: Detailed descriptions of the sample design, sample selection, and sample evaluation procedures have been presented in the "Zanzibar Working Report".
Response rates for pupils and schools respectively were 87% and 100%.
The calculation of sampling weights was conducted after all files had been cleaned and merged. Sampling weights were used to adjust for missing data and for variations in probabilities of selection that arose from the application of stratified multi-stage sample designs. There were also certain country-specific aspects of the sampling procedures, and these had to be reflected in the calculation of sampling weights.
Two forms of sampling weights were prepared for the SACMEQ II Project. The first sampling weight (RF2) was the inverse of the probability of selecting a pupil into the sample. These "raising factors" were equal to the number of pupils in the defined target population that were "represented by a single pupil" in the sample. The second sampling weight (pweight2) was obtained by multiplying the raising factors by a constant so that the sum of the sampling weights was equal to the achieved sample size.
Dates of Data Collection (YYYY/MM/DD)
Mode of data collection
Type of Research Instrument
The data collection for SACMEQ’s Initial Project took place in October 1995 and involved the administration of questionnaires to pupils, teachers, and school heads.
The pupil questionnaire contained questions about the pupils’ home backgrounds and their school life; the teacher questionnaire asked about classrooms, teaching practices, working conditions, and teacher housing; and the school head questionnaire collected information about teachers, enrolments, buildings, facilities, and management. A reading literacy test was also given to the pupils. The test was based on items that were selected after a trial-testing programme had been completed.
Data Entry and Data Cleaning
A team of eight persons from the Ministry of Education were appointed and trained in the use of WINDEM, a special data entry package to be used in SACMEQ. They were supervised by one person trained during the main training at IIEP Paris.
The numbers of keystrokes required to enter one copy of each data collection instrument were as follows: pupil booklet: 300; pupil reading test: 85; pupil mathematics test: 65; teacher booklet: 681; teacher reading test: 51; teacher mathematics test: 53; school head questionnaire: 319; school form: 58; and pupil name form: 51.
In the case of Zanzibar the total number of keystrokes was as follows: pupil booklet: 754,200; pupil reading test: 213,690; pupil mathematics test: 163, 410; teacher booklet: 247,203; teacher reading test: 9,945; teacher mathematics test: 9,116; school head questionnaire: 46,255; school form: 8,410; and pupil name form: 128,214. That is, a total of 1,580,443 keystrokes were required to enter all of the data for Zanzibar.
An experienced keyboard operator can work at a rate of 25 keystrokes per minute (working from multi-paged questionnaires and stopping occasionally to clarify individual questionnaire entries with the supervisor). Assuming that this kind of work rate could be sustained for, say, around a maximum of six hours per day, then the whole data entry operation for Zanzibar was estimated to amount to around 176 person days of data entry work. This implied an estimated five weeks of work for the eight-person data entry team that operated in Zanzibar. However, the work was completed in 28 weeks from November 2000 to June 2001 because only few computers were available for the work.
At the end of this procedure the data files were sent by e-mail to the 'Monitoring Educational Quality Unit' at the IIEP in Paris. Many consistency checks were made for many variables as well as for the identification codes used. The IIEP team had many queries. The first data files were sent to Paris in 15 June 2001 and after 27 cleaning cycles that took almost two years (22 months) of cleaning the files were finally declared to be clean on 23 April 2003.
