What is an Evaluator?

Do you find it difficult to explain to people what you do? Those magical two sentences that will get people to go "Aaaaaah, now I get what you do?" Unfortunately I have not been able to come up with something concrete yet. But I am still trying.

In a television interview to publicise the SAMEA conference, the DDG from the PSC Mr. Mash Dipofu tried to explain it with an example. He asked the TV presenter if he knew what the viewers thought of his programme, how it can be improved and how many people actually watches it. He explained that by answering these questions, you are doing what an evaluator would be doing and answering the underlying question: Does what I am doing have value?

Which got me thinking. So much of what we do as evaluators are also done by other professionals.

  • We are a little like investigative journalists: We talk to people and ask questions and gather information to make an argument for or argainst something. Sometimes to inform readers of some wrong doing... Sometimes we celebrate what has been achieved.
  • Then we are also a little like the weather guy. We collect numbers over a long period of time and by applying some statistical techniques we can start predicting what will happen in future.
  • Another way of looking at our job is to compare it to that of teachers. We guide people to learn from their environments - assuming that they need to be taught how to use the information at their disposal to make intelligent choices. We check with tests whether the intended result has been achieved... much like teachers check whether their students have mastered a skill or knowledge component.
  • And then of course evaluators are also a little like an auditor in the way that we try to prove to people that money has been well spent.

The problem with explaining to people what we do, is probably because people tend to confuse it with research and planning and implementation and all kinds of other things. I have also spent some time to think about how being an evaluator is different from being a researcher, a planner and an implementer.

  • Because we use research techniques to collect evidence in order to evaluate, the difference between being a researcher (who asks questions in a specific way to gather evidence) and an evaluator (who asks questions in a specific way to gather evidence to then make a value judgment about the evaluand) is sometimes a little difficult to explain. But there is a difference!
  • Planning, on the other hand comes quite naturally when you are an evaluator. After delivering an evaluation, I frequently get asked to assist in planning processes - if people value what you produced in the evaluation they want to make sure that they plan to implement the recommendations made. Being a weather guy and an auditor makes it easier to plan because you can draw info together to make predictions, and you know that you will have to explain to people why you chose to spend their money in a particular way.
  • I think evaluators will probably make terrible implementers. As an evaluator you are constantly asking questions: Is this the best way to do things? Will we achieve results? How would we know that we added value? How do we know that this is the best way forward? To implement, however, you sometimes have to say "Well I don't know all the answers but I am making a decision to do ABC in the following way and that is the way it is!"
Despite having useful analogies to explain what evaluators do and don't do, I think that we are at risk if we, as practitioners of a scientific metadiscipline, don't understand how the ideology underlying evaluation is different from other those informing other jobs. Evaluators might be sharing some commonalities with teachers, weather people, auditors and journalists, but we have different values and assumptions guiding our work. We cannot forget that our work probably has a deeply political nature because we have to choose at some stage whose questions we will have to answer.

I found the following useful bit about evaluation approaches and the underlying philosophy, epistemology and ontology at http://www.recipeland.com/facts/Evaluation

Classification of approaches

Two classifications of evaluation approaches by House House, E. R. (1978). Assumptions underlying evaluation models. Educational Researcher. 7(3), 4-12. and Stufflebeam & Webster Stufflebeam, D. L., & Webster, W. J. (1980). An analysis of alternative approaches to evaluation. Educational Evaluation and Policy Analysis. 2(3), 5-19. can be combined into a manageable number of approaches in terms of their unique and important underlying principles.

House considers all major evaluation approaches to be based on a common ideology, liberal democracy. Important principles of this ideology include freedom of choice, the uniqueness of the individual, and empirical inquiry grounded in objectivity. He also contends they all are based on subjectivist ethics, in which ethical conduct is based on the subjective or intuitive experience of an individual or group. One form of subjectivist ethics is utilitarian, in which “the good” is determined by what maximizes some single, explicit interpretation of happiness for society as a whole. Another form of subjectivist ethics is intuitionist / pluralist, in which no single interpretation of “the good” is assumed and these interpretations need not be explicitly stated nor justified.

These ethical positions have corresponding epistemologies—philosophies of obtaining knowledge. The objectivist epistemology is associated with the utilitarian ethic. In general, it is used to acquire knowledge capable of external verification (intersubjective agreement) through publicly inspectable methods and data. The subjectivist epistemology is associated with the intuitionist/pluralist ethic. It is used to acquire new knowledge based on existing personal knowledge and experiences that are (explicit) or are not (tacit) available for public inspection.

House further divides each epistemological approach by two main political perspectives. Approaches can take an elite perspective, focusing on the interests of managers and professionals. They also can take a mass perspective, focusing on consumers and participatory approaches.

Stufflebeam and Webster place approaches into one of three groups according to their orientation toward the role of values, an ethical consideration. The political orientation promotes a positive or negative view of an object regardless of what its value actually might be. They call this pseudo-evaluation. The questions orientation includes approaches that might or might not provide answers specifically related to the value of an object. They call this quasi-evaluation. The values orientation includes approaches primarily intended to determine the value of some object. They call this true evaluation.

Rant for today*

A potential client sends out Terms of Reference requesting potential service providers to submit a quotation for an (5 maybe 10 person day) evaluation engagement. Note, they did not ask for a proposal, they asked for a quotation. Given the limited scope of the project, a quotation makes sense. So that is what I submit.

Then potential client reads through the proposals they received and *Horror* *shock* discovers that there isn’t enough information in the quotations to make a transparent decision. (Maybe there was a little problem with the Terms of Reference?) They then set up a meeting in which they expect potential service providers to present to a panel. “For the purposes of meeting with the potential evaluators and ensuring the selection process is fair and transparent”. (Have I mentioned that this is a small job?)

So I go and have a wonderful meeting with the potential client, but in the end do not get the job. My heart isn’t broken or anything. It would’ve been nice to get the job but… ah well, I think they looked for a content specialist rather than an evaluation specialist in the first place.

But hey, I am an evaluator, and evaluative thinking requires me to find out why I was not successful. So I write the “Thanks for the notification, we are disappointed, could you please tell us where our submission was weak… bla-di-blah” email. To which I don’t receive a response. I get my office manager to follow up and get a response of the kind: “We liked your presentation / Sorry we don’t have time to provide feedback / now please just leave us alone”.

What happened to the transparency and fairness thing? Am I unreasonable to think that a two line explanatory email is not much to ask after all of the trouble they put me through?

Ahem… The UK evaluation Society has some guidelines for persons when they commission evaluations at:

http://www.evaluation.org.uk/Pub_library/PRO2907%20-%20UKE.%20A5%20Guideline.pdf

Maybe more people should read that?

*Because this is my blog I get to complain here every now and again. I promise that this will not turn into those rant-upon-rant blogs, but I really need to get the following off my chest.

Whew! Its been like how long?

I see I haven't posted anything here since April. That is probably because I have nothing to write about when I have time, and when I have time to write, I can't think of anything to write about. So here are a list of things I would like to address at some stage:

* What people think a focus group is and what it really is
* Rapid assessment methods - differences in approaches (I need to draw up a table based on that AJE article I read yesterday)
* When people should consider appointing an evaluation specialist rather than a content specialist for certain evaluations.
* If evaluators do strategic planning, what is it that they should know about planning AND if planners or anybody else does evaluations what is it they need to know about evaluations
* People say evaluation is a meta-discipline. Why do they say that.
*All this talk about accreditation is just confusing everybody. What does it mean and what about the international body of work that has been done on this aspect?

Handy Publication: New Trends in Evaluation

You know how you always come back with a stack of stuff to read when you've attended an evaluation conference? It most cases the material just gets added to my ever growing "to read" pile. It is only once I start searching for something or decide to spring-clean, that I actually sit down and read some of the stuff. This morning I came across a copy of UNICEF / CEE/CIS and IPEN's New Trends in Evaluation.

What a delightfully simple straightforward publication - yet it packs so much relevant information between its two covers. I wish I had remembered about it last week when I lectured to students at UJ. Before I was able to get on with the lecture on Participatory M&E, I first had to explain how M&E is different and similar to Social Impact Assessments (In the sense of ex-ante Environmental Impact Assessment type assessment). I think it would have been a very handy introductory source to have.

The table of contents looks as follow:

1. Why Evaluate?
The evolution of the evaluation function
The status of the evaluation function worldwide
The importance of Evaluation Associations and Networks
THe oversight and M&E function
2. How to Evaluate?
Evaluation culture: a new approach to learning and change
Democracy and Evaluation
Democratic Approach to Evalution
3. Programme Evaluation Development in the CEE/CIS

But what is really useful is the Annexures:
Annex 1: Internet Bades Discussion Groups Relevant to Evaluation
Annex 2: Internet Websites Relevant to Evaluation
Annex 3: Evaluation Training and Reference Sources Available Online
Annex 4-1: UNEG Standards for Evaluation in the UN System
Annex 4-2: UNEG Norms for Evaluation in the UN System
Annex 5: What goes into a Temrs of Reference; UNICEF evaluation Technical Notes, Issue No.2

The good thing about this publication is that you can download it for free off the internet at

http://www.unicef.org/ceecis/New_trends_Dev_EValuation.pdf

An introductory blurb and a presentation is also available from the IOCE website.

Presentation Presented at the SAMEA conference 26 - 30 March 2007

Based on some of the ideas in previous blog entries, I presented the following presentation at the recent SAMEA conference.

Setting Indicators and Targets for Evaluation of Education Initiatives

Introduction

  • Good Evaluation Indicators and Targets are usually an important part of a robust Monitoring and Evaluation system.
  • Although evaluation indicators are usually considered as important, all evaluations do not have to make use of a set of pre-determined indicators and targets.
  • The most significant change (MSC) technique, for example, looks for stories of significant change amongst the beneficiaries of a programme, and after the fact uses a team of people to determine which of these stories represent MSC and real impact.
  • You have to include the story around the indicators in your evaluation reports in order to learn from the findings.
What do we mean?
  • The definition of an Indicator is: “A qualitative or quantitative reflection of a specific dimension of programme performance that is used to demonstrate performance / change”
  • It is distinguished from a Target which: “Specifies the milestones / benchmarks or extent to which the programme results must be achieved”
  • And it also different from a Measure which is: “The Tool / Protocol / Instrument / Gauge you use to assess performance”
Types of Indicators
  • The reason for using indicators is to feel the pulse of a project as it moves towards meeting its objectives or to see the extent to which it has been achieved. There are different types of indicators:
  • Risk/enabling indicators – external factors that contribute to a project’s success or failure. They include socio-economic and environmental factors, the operation and functioning of institutions, the legal system and socio-cultural practices.
  • Input indicators – also called ‘resource’ indicators, they relate to the resources devoted to a project or programme. Whilst they can flag potential challenges, they cannot, on their own determine whether a project will be a success or not.
  • Process indicators – also called ‘throughput’ or ‘activity’ indicators. They reflect delivery of resources devoted to a programme or project on an ongoing basis. They are the best indicators of implementation and are used for project monitoring.
  • Output indicators –indicates whether activities have taken place by considering the outputs from the activities.
  • Outcome indicators - indicates whether your activities delivered a positive outcome of some kind.
  • Impact indicators – Concerns the effectiveness, usually long term, of a programme or project as judged by the measurable achieved in improving the quality of life of beneficiaries or other similar impact level result.
Good Indicators
  • Good Performance Indicators should be
  • Direct (Does it measure Intended Result?)
  • Objective (Is it ambiguous?)
  • Adequate (Are you measuring enough?)
  • Quantitative (Numerical comparisons are less open to interpretation)
  • Disaggregated (Split up by gender, age, location etc.)
  • Practical (Can you measure it timeously and at reasonable cost?)
  • Reliable (How confidently can you make decisions about it?) (USAID, 1996)
SMART Indicators
Most people have also heard about SMART indicators:
  • Specific
  • Measurable
  • Action Oriented
  • Realistic
  • Timed
How we use indicators
  • For many of the evaluation initiatives that we help to plan M&E systems for, we usually work with the managers to set indicators that they understand and can use.
  • Although the issue of data availability and data quality is usually a big concern, it is often the indicators and targets that are set that could make or break an evaluation.
Case Study
  • Implementers of a teacher training initiative wants to know if their project is making a difference in the maths and science performance of learners.
Pitfalls
  • Alignment between Indicators & Targets (If the indicator says something about a number, then the target must also be couched in terms of a number, and not a percentage)
  • Averaging out things that do not belong together (i.e. maths and science) does not make sense at all.
  • Not disaggregating enough (Are you interested in all learners, or is it important to look at disaggregating your data by age group, gender, educator)
  • Assuming that all targets should be about an increase: (Sometimes a trend in the opposite direction exists and it is expected that your programme will only mediate the effects)
  • Assuming that an increase from 20% to 50% is the same as an average increase of 50% to 80%. (Psychometrists have used the standardised gain statistic for a very long time. It is interesting that we don’t see more of it in our programmes.)
  • Ignoring the statistics you will use in analysis: (In some cases you are using a sample and averages. This means an average increase might just look like an increase, but when you test for statistical significance it is actually not an increase)
  • Setting indicators that require two measurements where one would be enough (Are you interested in an average increase, or just the % of people that make some minimum standard.)
  • Ignoring other research done on the topic (If a small effect size is generally reported for interventions of these kinds, isn’t an increase of 30% over baseline a little ambitious?)
  • If you don’t have other research on the topic, it should be allowable to adjust the indicators.
  • Setting an indicator and target that assumes direct causality between the project activity and the anticipated outcome (Even if you have brilliant teachers, how must the learners perform if learners have nowhere to do homework, School discipline is non-existent and after learners have accumulated 10 years of conceptual deficits in their education?)
  • Ignoring Relevance, efficiency, sustainability, and equity considerations. (Is educators training really going to solve the most pressing need?If your programme makes a difference, is it at the same cost as training an astronaut?What will happen if the trained educator leaves?Does the educator training benefit rural learners in the same way in which it would benefit urban learners?)
Ways to address the pitfalls
  • Do a mock data exercise to see how your indicator and target could play out.
  • This will help you think through the data sources, the statistics, and the meaning of the indicator
  • Read extensively about similar projects to determine what the usual effect size is.
  • When you do your problem analysis, be sure to include other possible contributing factors, and don’t try to attribute change if it is not justifiable.
  • Look at examples of other indicators for similar programmes
  • Keep at it and work with someone who would be able to check your proposed indicators with a fresh eye.
Where to look
Example Indicators can be found in:
  • Project / Programme Evaluation reports from multi-lateral donor agencies
  • UNESCO Education For All Indicators
  • Long term donor-funded projects such as DDSP, QIP.
  • StatsSA publications and statistical extracts about the education sector.
  • Government M&E indicators.
