Why can't self-rating and internal pre-assessment replace third-party evaluation?

Thursday, November 20, 2025

In many private initiatives, projects are first “pre-evaluated” by advisors, assessors, or an internal network before being presented as evaluated by an external body. This structure never guarantees impartiality, as the production and verification of evidence are carried out within a closed system. An independent evaluation requires a strict separation of roles and an accreditable third party.

1. The pre-assessment creates a direct influence on the decision

In self-managed systems, the sequence is often as follows:

  1. a network stakeholder is supporting the project;
  2. he participates in the production of evidence;
  3. he prepares a preliminary file or a preliminary assessment;
  4. he transmits his information to an evaluator;
  5. The case is then processed using the same methodological approach.

This organization creates a structural influence:

  • The project is guided by internal understanding.
  • The file is optimized according to the network's doctrine.
  • The evidence is prepared with the objective of a conformity known in advance.

Consequence:

The evaluation can no longer be independent.

2. Involving a subcontractor does not create an independent third party

Several private schemes involve external structures for “evaluation”. But these actors:

  • apply the designer's method,
  • follow his interpretations,
  • do not control governance
  • are not accredited to certify this method,
  • are not independent of the system,
  • do not have a mandate for impartial decision-making.

They act as:

  • providers,
  • operators,
  • internal controllers, not as an independent third party.

The legal status is not that of an ISO accredited body.

It's subcontracting, not independence.

3. A Participatory Guarantee Scheme (PGS) is not a third-party assessment

A SGP is based on:

  • peer review,
  • community assessment,
  • internal legitimation,
  • the network consensus.

This model:

  • is not independent,
  • is not enforceable,
  • is not accreditable,
  • is not compatible with public policies,
  • is not usable by institutional investors.

A SGP is a mechanism for internal cohesion, not an impartial evaluation.

4. Self-assessment + internal pre-evaluation = lack of impartiality

In these systems, the accompanying person:

  • optimizes the project,
  • design assistance,
  • prepare the evidence.
  • selects the items to be provided,
  • influences how the criteria will be read.

Then an evaluator (external or not) receives a file already directed by the network.

Neutrality is lost:

  • the evidence is not independent,
  • The interpretation is predefined.
  • Compliance is anticipated.
  • Analysis is no longer free.

This is the exact opposite of what a third-party evaluation requires.

5. Why is this model incompatible with ISO 17065?

ISO 17065 requires:

  • independence of the evaluation,
  • impartiality of the process,
  • absence of a dual role,
  • Separate governance
  • impartial decision
  • control by a national accreditation body.

The diagram:

Support → Pre-assessment → Assessment → Decision in a closed system

rape:

  • independence,
  • impartiality,
  • the traceability of evidence,
  • the separation of roles,
  • Decision-making neutrality.

Result :

Device not accreditable.

6. Without an independent third party, the evidence is not institutionally admissible.

European requirements (CSRD, Taxonomy, SFDR) require:

  • an audited piece of evidence
  • an independent third party,
  • a governance free from influence,
  • a methodology verifiable by a public authority.

An internal pre-assessment:

  • directs the evidence,
  • eliminates neutrality,
  • prevents impartial verification
  • makes the data unsuitable for integration into ESG financing.

Project owners, local authorities and investors cannot rely on it.

7. The independent model: separate production of evidence from the evaluation

The IRICE structure perfectly meets institutional expectations:

Biodiversity Partners

→ accompany → prepare the evidence → document → never evaluate.

IRICE Assessors

→ check → control → apply the ISO procedure → never accompany.

IRICE Decision

→ taken over by an independent entity.

Result :

Support ≠ Evaluation ≠ Decision → demonstrable impartiality.

Conclusion

Self-assessment and internal pre-evaluation do not replace an independent third party. Whether it is an assessor, an internal network, an external service provider, or a Participatory Guarantee System, the evidence remains produced and pre-validated within the system.

Only a strict separation between support, evaluation and decision-making, in accordance with ISO requirements, can guarantee an impartial, accreditable and institutionally acceptable evaluation.
