GEOS-FN-008 — GEOSor™ Certification Body of Knowledge (Foundational Numeracy)

GEOS-FN-008 — GEOSor™ Certification Body of Knowledge (Foundational Numeracy)

Version: 0.01 Status: Normative Standard (Institutional Enablement)

0. Interpretive Basis ————————-

GEOS-FN-008 defines the Body of Knowledge (BoK) required for an individual professional to be certified as a GEOSor™ for the assessment of Foundational Numeracy Outcome Signal Portfolios submitted for certification under GEOS-FN standards.

This document:

• defines required knowledge domains and competencies;

• supports consistent, reproducible conformity assessment across jurisdictions;

• enables scale without expanding The GEOS Organization's institutional capacity; and

• applies only to professional certification of assessors.

This document:

• does not define outcome standards;

• does not define assessment procedures (see GEOS Assess documents);

• does not grant authority to assess any artifact absent formal accreditation; and

• does not constrain School Systems, Data Source Operators, or Finance Facilities.

1. Certification Scope ————————--

A GEOSor™ certified under GEOS-FN-008 is qualified to assess:

• Outcome Signal Portfolios submitted for certification as GeOSPs™;

• conformity with GEOS-FN-001 through GEOS-FN-007; an

• auditability, reproducibility, and contestability requirements specific to Foundational Numeracy.

Certification under this BoK is domain-specific.

GEOSor™ certification for other domains (e.g., literacy) requires separate BoKs.

2. Required Competency Domains ———————————-

A candidate for GEOSor™ certification MUST demonstrate mastery of all competency domains below.

2.1 GEOS System Architecture

Knowledge of:

• GEOS role boundaries (per GEOS-CORE-001;

• separation of standards definition, conformity assessment, and funding;

• artifact-centric certification logic; and

• voluntary participation and authority limits.

2.2 Foundational Numeracy Domain Knowledge

Knowledge of:

• globally recognized Foundational Numeracy constructs;

• the construct families defined in GEOS-FN-001 and GEOS-FN-002;

• common sources of construct contamination and proxy misuse; and

• known measurement weaknesses at early grade levels.

This domain emphasizes measurement literacy, not pedagogy.

2.3 Outcome Signal Theory

Knowledge of:

• status vs. progress signals;

• distributional vs. point estimates;

• cohort vs. learner-linked growth;

• statistical artifacts that induce gaming; and

• signal portfolio logic under anti-gaming constraints.

2.4 Data Pipeline and Transformation Logic

Knowledge of:

• Layer A, Layer B, and Layer C distinctions;

• permitted transformations under GEOS-FN-004;

• depersonalization rules and audit reconstruction;

• reproducibility and versioning requirements; and

• failure modes in automated aggregation.

2.5 Auditability and Evidence Evaluation

Knowledge of:

• audit trail completeness requirements;

• reproducibility testing techniques;

• immutability verification;

• red-flag patterns indicating manipulation; and

• evidentiary sufficiency under GEOS standards.

2.6 Contestability and Re-Assessment

Knowledge of:

• dispute triggers and admissible challenges;

• re-assessment boundaries;

• reassessment independence rules; and

• procedural neutrality requirements.

2.7 Ethics and Conflict-of-Interest Management

Knowledge of:

• independence requirements for assessors;

• prohibited dual roles;

• disclosure obligations;

• assessor recusal conditions; and

• sanctions and revocation triggers.

3. Examination Requirements ——————————-

GEOSor™ certification MUST be granted only upon successful completion of:

• a written examination covering all competency domains;

• scenario-based assessment exercises involving simulated GeOSPs™;

• reproducibility and audit reasoning tests; and

• ethics and conflict-of-interest evaluations.

The GEOS Organization publishes examination blueprints and may choose to administer examinations directly, indirectly, or both.

4. Certification Maintenance ——————————--

A GEOSor™ certified under GEOS-FN-008 MUST:

• complete periodic recertification;

• demonstrate familiarity with updated GEOS-FN standards;

• maintain continuing education credits; and

• comply with all disclosure and independence requirements.

Failure to meet maintenance requirements MUST result in suspension or revocation.

5. Relationship to GEOSor™ Certified Partners™ ————————————————--

This BoK:

• applies to individual professionals, not firms;

• underpins accreditation of GEOSor™ Certified Partners™;

• does not substitute for organizational accreditation; and

• does not authorize unsupervised certification activity.

6. Authority Limits ———————--

Certification under GEOS-FN-008:

• authorizes assessment activity only within GEOS-defined procedures;

• conveys no authority over funding decisions;

• conveys no authority over outcome definition; and

• does not imply endorsement of any School System or program.

7. Versioning and Evolution ——————————-

This Body of Knowledge:

• is versioned independently of FN outcome standards;

• evolves based on audit findings and system learning; and

• preserves backward interpretability where feasible.
