Desk review
The first step of a social impact assessor's fieldwork: examining an organisation's existing documents — reports, policies, photographs, prior data — before any physical inspection or interview.
In plain language
Before a social impact assessor ever visits a project site, there is a stack of paper — or files — already sitting in the organisation's own records. Working through that stack first is the desk review.
Every case study in the workbook's Chapter 8 begins its evaluation with one. The workbook's own words, from the IWMP case study: "A desk review of existing documents was conducted to gain further insight into the evaluation procedure and impact assessment."
It is always the first step, ahead of physical inspection and personal interviews — the workbook's case studies are consistent about this ordering across water, education, health and housing projects alike.
How it works
The desk review draws on the organisation's own secondary sources — documents it already holds, rather than new data collected in the field. The workbook's IWMP case study lists exactly what kind of documents count:
- Reports generated under environment protection laws
- Annual reports
- Sustainable development curriculum materials
- Feedback forms from staff and trainees
- Photographs of activities carried out
- Data on improved soil fertility, rainfall and agricultural productivity
- Plans and programmes held, and planned for the future
- The organisation's own policy documents (in this case, its Water Conservation Management Policy)
Once the desk review is complete, the workbook moves to physical inspection (checking dams, borewells, farm ponds and pipelines directly) and personal interviews with selected stakeholders — the desk review sets up the questions these later steps are designed to answer, rather than replacing them.
A worked example
AB Responsible Services, an NPO running the Integrated Water Management Project across 18 villages in Ratnagiri and Raigad, with a population of 25,000 and a total investment of ₹45.3 lakh, is assessed by a social impact assessor who begins with a desk review of the organisation's environment-law reports, annual reports, water-conservation policy and photographs of the check dams and farm ponds already built.
Only after this desk review does the assessor move to physical inspection of the check dams and borewells, and to fieldwork — 20 focus group discussions, 10 key informant interviews and 500 quantitative surveys with a 5% sample of direct beneficiaries across the 18 villages.
The desk review does not replace this fieldwork. It gives the assessor context — for instance, knowing from the Water Conservation Management Policy what the project's own stated targets were — so the physical inspection and interviews that follow can be designed to actually test whether those targets were met.
Why NISM asks about it
Chapter 8 (Social Impact Assessment Case Studies), section 1.30 of each worked case study, opens the evaluation methodology with a desk review before physical inspection and interviews. Expect a question on the correct sequencing of assessment steps (desk review first) and on what kind of sources a desk review draws on (existing organisational documents, not new field data).
Common exam traps
- Desk review always comes first, before physical inspection and interviews, in every case study in this chapter — a question on assessment sequencing is testing exactly this order.
- Desk review uses secondary sources — the organisation's own existing documents — not primary data collected fresh from stakeholders, which belongs to the interview and survey stages.
- A desk review is not a substitute for physical inspection. The workbook explicitly treats them as separate, sequential steps — a desk review alone would not confirm whether, for instance, a check dam was actually built to specification.
- Do not confuse desk review with the engagement file, which is the assessor's own documentation of the engagement — a desk review examines the client's documents; the engagement file records the assessor's work.
Check yourself
1.Which set of data collection tools is used repeatedly across the workbook's case studies?
- a)Key Informant Interviews, Focus Group Discussions and quantitative surveys
- b)Stock market data, credit ratings and balance sheets
- c)Satellite imagery, drones and sensors only
- d)Only secondary data from government websites
Show the answer
Answer: (a) Key Informant Interviews, Focus Group Discussions and quantitative surveys
The watershed, eye-care and women's health cases all use Key Informant Interviews (KII), Focus Group Discussions (FGD) and quantitative surveys, supported by desk review and inspection.
The other options either have nothing to do with social impact data or ignore the primary data collection that every case relies on.
2.In the workbook's case studies, key metrics for evaluating a project are collated from which assessments?
- a)End-line assessments only
- b)Baseline, mid-line (monthly / quarterly) and end-line assessments
- c)Donor reports only
- d)Annual financial statements only
Show the answer
Answer: (b) Baseline, mid-line (monthly / quarterly) and end-line assessments
The cases say key metrics were collated from baseline, mid-line (monthly / quarterly) and end-line assessments to understand and evaluate impact.
End-line alone cannot show change, because there is nothing to compare against. Donor reports and financial statements may feed a desk review but are not where key metrics come from.

- Baseline, mid-line and end-lineThe three-point measurement sequence — before, during and after an intervention — the assessor uses across the workbook's case studies to collate key metrics and evaluate what actually changed.
- Direct beneficiariesThe people directly reached by a programme's activities — such as villagers, farmers and local business owners — as distinct from indirect beneficiaries who benefit at one remove.
- Engagement fileThe assembled record — hard copy or soft copy — of an assessor's engagement documentation, which must be completed within about 60 days of the social impact assessment report and then kept, not discarded.
- BaselineThe starting-point measurement of a project or programme, taken before an intervention begins, used to establish what actually changed as a result of it.
- Constraint on impactAn external factor — such as a market or demand-side mismatch — that limits how much impact a project can achieve, distinct from a challenge in conducting the social impact assessment itself.
