CESAR provides consultancy services in all aspects of research and evaluations from inception to completion. This includes research designs, designing monitoring and evaluations systems, technical reviews, programme evaluations, questionnaire validation, data collection, data capture, data analysis and report writing.

Our expertise is research surveys, evaluations, programme science, data quality and use for experimental and quasi-experimental techniques for impact evaluation. Our strongest points are our expertise and absolute dedication to rigour. This starts from attention to the research design to the field work and data analysis. We understand the potential threats to research validity and guard against them throughout the lifetime of the project.

Research Designs

We are experts in the use of different research designs to answer research questions needed to solve existing problems in health, education and allied field. Our researchers have been involved in the design and analysis of over a hundred research projects in different parts of the world. Specifically, in South Africa and beyond, we have conducted research projects in the aforementioned sectors. As a result, we have in-depth understanding of development issues and drivers of change affecting the continent.

Evaluation Designs

We are experts in the use of experimental and non-experimental designs for evaluating the impact of interventions. We understand the science of intervention and provide support with designing and evaluating the impact of intervention programmes. The central theme in impact evaluation is cause-and-effect attribution. We know the common threats to attribution, and so using the programme logic model and setting, we ensure a rigorous design that will enhance research validity. We are experts in creating counterfactual groups at the design and/or analysis stage of evaluation research.

Research Surveys

We have conducted different types of research surveys from surveys using small convenient samples to large national surveys using probabilistic sampling. Our strongest points for research surveys are our expertise and experience in research designs and statistics, as well as our dedication to rigour. We start by ensuring that the research design can answer the research questions and ensure that validity is a key focus in the data collection and data analysis. We understand the potential threats to research validity and guard against them from inception to completion.

Data collection

The quality of any research ultimately falls on the quality of the data collected. CESAR specializes in collecting quality research data for three reasons:

  • we absolutely understand the value of quality data since we are also researchers and statisticians;
  • we have access to a pool of data collectors who have tertiary qualification
  • we have strong quality assurance procedures for research fieldwork.

Research Databases

We design databases for clients who want to capture their data themselves. We use simple software like Microsoft Access, Epi-Info, Epi-Data and more advanced software depending on the size and needs of the project. All databases can be customized to client’s needs – with range checks, skip patterns, etc. – in order to allow for accuracy and efficiency.

Data Capture

CESAR provides data capture services to research and business organisations. For the same reason we collect high quality research data, we also produce excellent output in data capture. Our data capturers are trained and supervised. CESAR also provides training for data capturers, for example, our course Professional Course in Data Capture has benefited organisations that employ data capturers

Data Analysis

Many organisations often have large amount of unanalysed data. Yet, data analysis and interpretation can significantly improve the quality of work done, service rendered and number of lives impacted. At CESAR, we primarily use Stata for data analysis. Stata is arguably the best software for data management and statistical analysis. We also have many years of experience in collecting and analysing qualitative. We use Nvivo for qualitative data analysis. data.

DescriptionCESAR was commissioned by Word of Mouth Productions to conduct a rapid evaluation of a 13-episode TV drama series on road safety in South Africa. The evaluation utilised Focus Group Discussions (FGDs) to get feedback on aired and unaired episodes of the series. The study sought to understand how road users perceive the drama episodes. This evaluation provided important feedback to the scriptwriters and production staff of the social and behavioural change television programme.

The Department of Basic Education (DBE) has partnered with the United Nations Children’s Fund (UNICEF) to conduct a Baseline Study and Action Research on the implementation of play-based learning in early childhood development (ECD) and foundation phase (FP) of education. CESAR was contracted by Khulisa Management Services to conduct data collection for the study. The baseline study set out to capture existing conditions before the roll out of the intervention. This intervention and evaluation is sponsored by UNICEF.

Description Truck drivers have unique health needs and experience difficulties in accessing healthcare. Currently, planning for effective care is hindered by lack of knowledge about their health needs. A cross sectional study of long distance truck drivers was conducted to provide insight into the risk factors and diseases which impact the health of South African men. CESAR was contracted after the survey to conduct data cleaning, management and analysis for the project.
Client Wits Reproductive Health Institute (WRHI).
Description CESAR captured questionnaire data for 635 Learners and utilised double capture and data compare to ensure high data quality. CESAR conducted quantitative and qualitative analysis on the data and submitted completed a full report on the research findings. The data forms part of HWSETA M & E work.

DescriptionUNAIDS Zimbabwe contracted CESAR’s Research Technical Leader to conduct an epidemiological synthesis of the HIV epidemic in Zimbabwe. This epidemiological data analysis was commissioned to provide recent evidence to inform the revision of the Zimbabwe National AIDS Strategic Plan (ZNASP). The last comprehensive analysis was carried out in 2010 and has since been overtaken by events. Therefore, the goal of this synthesis was to understand the changes that have taken place since 2010 and identify current extent and drivers of the epidemic with the aim of making recommendations for the national response
