Across our five pillars
Measures matched to the work

What each pillar measures

TEEI’s five pillars cover education, health equity, research, advocacy and compliance. Each uses measures suited to its work, from learning and social connection to research outputs, institutional contributions and partner reporting.

Programme Delivery22Outcome7Experience4Access6Stewardship16

Education

37 measures · 32 values available

We track one-to-one and group learning, credentials, partner-platform participation, recorded language levels, learner confidence and continued participation.

The published session method explains how attendance records become completed sessions and verified conversation hours.Explore the session method

Health Equity

draft protocol published · 1 planned measure

One Connection’s draft study protocol sets out how recruitment, matching, relationship continuity and participant outcomes will be assessed.

It specifies UCLA-3, PHQ-9, GAD-7, FACT-BMT and PROMIS social isolation, with planned ClinicalTrials.gov registration before enrolment and CONSORT reporting for pilot trials.Read the One Connection protocol

Research

first output published · 1 planned reporting measure

Research reporting covers TEEI’s protocols, studies, datasets and software, together with their documented use.

The first published output is the L2SAFE pilot: 24 paired items, an eight-item safety subset and analysis of the discordant pair. The planned register will track published outputs and their use.Explore the L2SAFE pilot

Advocacy and Policy

six published streams · 1 planned measure

Six advocacy streams connect TEEI’s programme experience with published research.

The planned contribution register will document published positions, institutional responses and changes in practice, with dates, supporting sources and contributing actors.Explore the advocacy streams

Compliance

Measurement standards
Four reporting principles

How our figures are produced

Our reporting principles connect published figures to their source records, protect participant information and document the methods used.

Attendance-based counting

Current-platform session totals use settled attendance records. Sessions awaiting evidence appear separately in the counter, 7 of them as this page loaded.

Documented corrections

Corrections identify the revised figure and the publication they update.

Participant privacy

Small-group figures are published as ranges or withheld to protect participant privacy.

Versioned methods

Published methods carry a version identifier, linking reported figures to the calculation used.
