Measured value — fictional 2025 examples

Method. Compare the measured value only with matching parameter, unit, use and averaging period. Retain limit source/version and censored-result status.

Next step. Within example comparison bounds. Refer a confirmed nonconformance for authorized response, resample, or investigate the method.

Inputs, example and sources

Keep the same place, observation period, definitions, units and source versions.

Analysis inputs. Parameter and applicable use; Measured result [pH]; Example lower comparison bound [pH]; Example upper comparison bound [pH]; Original and limit unit; Sampling and analytical method/version; Limit source, version and use; Parameter, unit, use and averaging period match; Result is below a reporting/detection limit; Averaging interval, sampling depth or process basis

Verified coverage — fictional 2025 examples

Method. 100 × distinct covered eligible units / eligible frame. Known uncovered = frame − covered − unknown.

Next step. Review evidence. Select eligible underserved units for outreach, investigate missing coverage, or revise the verified frame.

Inputs, example and sources

Keep the same place, observation period, definitions, units and source versions.

Analysis inputs. Required eligible frame [samples]; Distinct members of that frame covered [samples]; Frame members with unknown coverage [samples]

Other required evidence. Target institutions; findings; training participation; follow-up compliance; location.

Method. (Treatment after−before) − (comparison after−before), using the same outcome definition and periods.

Next step. Supply study-design evidence. Continue, adapt, expand or stop a programme based on defensible outcome evidence.

Inputs, example and sources

World Bank · Impact Evaluation in Practice Second Edition
Institution publication · Chapter 7, table 7.2, printed page 140, PDF page 170

The formula is verified. Causal interpretation still requires a defensible study design, comparison and assumptions.

Keep the same place, observation period, definitions, units and source versions.

Analysis inputs. Treatment Selected water-quality parameter before [mg/L]; Treatment Selected water-quality parameter after [mg/L]; Comparison Selected water-quality parameter before [mg/L]; Comparison Selected water-quality parameter after [mg/L]; Study design and comparability evidence; Outcome definition, method and reference basis

Other required evidence. Baseline quality; follow-up; reference sites; intervention dates; external pressures.

5. Documents and images

Your institution has its own document and image library. Use the same library for reports, photos and other evidence.

Central Environmental Authority Documents and images prototype screen
Central Environmental Authority. Prototype screen. Select the image to enlarge it.

What you can try

  1. Open Documents and images. Check the institution name.
  2. Use All files, Documents or Images to find a file. Open its preview or download the original.
  3. Use a sample file to try Add file. Private is the starting choice. Public needs a source, permission to share and review.
  4. Use Access preview to try the institution reviewer and Public visitor views.

Files added in the prototype stay in this browser. Public sharing is an access preview. Existing public reference links already work online.

What your institution needs to confirm

6. Data structure management

Data structure keeps the existing source tree, records, charts and map. Manage structure adds a place to propose changes to definitions.

Central Environmental Authority Data structure management prototype screen
Central Environmental Authority. Prototype screen. Select the image to enlarge it.

What you can try

  1. Open Data structure and choose Manage structure.
  2. Use Add base domain for a main information area. Add inside creates a subject area, a nested subject, an entity type or a field under the right parent.
  3. Give the definition a clear name, code and meaning. Reuse an existing definition when the meaning is the same.
  4. For a field, check the data type, unit, required value, limits and missing-value rule. Save a Draft, then try the separate reviewer view.

An entity type means a kind of thing or event, such as a reservoir or an inspection. Drafts stay in this browser. A demo approval does not change real definitions, data, chart links or sharing rights.

7. Users and access

User management shows example profiles for each institution. People and Roles and access let you review the proposed account screens.

Central Environmental Authority Users and access prototype screen
Central Environmental Authority. Prototype screen. Select the image to enlarge it.

What you can try

  1. Open User management and choose the institution. The rows are examples, not a list of your staff.
  2. Use View access to check a role. An administrator title alone does not give access to Private files.
  3. Try Preview invitation or Preview access change. Check the role, start date, optional end date and reason.
  4. Review the example permissions and tell us which job roles should receive each one.

These are interface previews only. They create no account, send no email and change no access. Use example details in the preview. Institution verification does not grant a real permission.

What your institution needs to confirm

8. Can you share data regularly?

We currently use public data and published reports where available. Please confirm whether your institution can provide data directly, so we can avoid retyping or reading figures from PDFs.

Do not enter passwords, access keys or private account details.
