The (project) intervention logic (or logic model) explains and illustrates the overall concept of a project and explains how change takes place, starting from the identified needs for project interventions to the expected impacts that would reduce the needs.

Affiliated entities are entities that are legally/economically linked to a beneficiary and contribute to the implementation of projects. Affiliated entities are named and budgeted in the grant agreement, but do not sign it. Affiliated entities can claim costs as part of the regular reporting.

The applicant is a person or organisation (or consortium) applying for EU funding.

Associated partners are institutions that are assigned to a partner and participate in the implementation of the project free of charge. Associated partners do not sign the grant agreement and therefore have no possibility to claim costs.

The beneficiary is the person or organisation applying for/receiving EU funds in the form of a grant.

The budget is the estimate of the total eligible costs (broken down by project beneficiary and budget category) necessary to carry out the project and, if approved, form part of the grant agreement. The four main budget categories are personnel costs, subcontracting costs, acquisition costs (incl. travel costs) and other costs.

The Call for Proposals is the procedure by which applicants are invited to submit project proposals in order to apply for EU funding.

A consortium is a group of beneficiaries applying for EU funding or implementing a project. Some programmes have mandatory rules for the composition of consortia, e.g. a minimum number of consortium partners, or they do not allow certain types of roles in a consortium. Therefore, the specific programme guidelines must always be consulted.

One of the consortium partners must be the project coordinator, also known as the lead applicant, who is the main contact person for the funding body throughout the project.

Eligibility criteria are rules set out in a programme that beneficiaries must follow when designing and implementing their projects. Compliance with the eligibility criteria is a prerequisite for receiving EU funding.

Financial support for third parties or "cascade funding" is a mechanism to distribute funding to support beneficiaries such as start-ups, scale-ups, SMEs and/or mid-cap companies to launch or develop digital innovations. It allows applicants to reach and involve a large number of legal entities that would not normally participate in the funding programme and opens participation to a wider range of potential stakeholders. Funding (in the form of grants, prizes or similar forms of support) is provided by the beneficiary(ies) to so-called "third parties" who are not party(ies) to the grant agreement. Actions can only include financial support to third parties if this is explicitly allowed in the work programme/call.

The JS is the body responsible for the day-to-day implementation of the programme; its tasks are often carried out under the responsibility of the Managing Authority. The Joint Secretariat is usually specialised in all communication down to the project level and in processing the reporting information received from the projects to the projects.

The LEAR is the person nominated by an organisation to manage its data in the portal and to manage and keep the organisation's data up to date.

NCPs are a network of national bodies (in the EU Member States and associated countries) that provide applicants with individual advice on funding instruments on the spot.

The classification of territorial units for statistics (Nomenclature des Unités territoriales statistiques - NUTS) divides the territory of the European Union into three hierarchical levels: NUTS-1, NUTS-2 and NUTS-3. This classification allows cross-border statistical comparison of EU regions.

• NUTS 1: large socio-economic regions
• NUTS 2: basic regions for the application of regional policy
• NUTS 3: small regions for specific diagnoses

Proposals may be submitted in one or two steps. For one-step submissions, applicants must submit a full proposal at the time of the submission deadline. For two-stage submissions, applicants submit a short proposal on the day of the first deadline, which is evaluated. If the first evaluation stage is passed positively, applicants are invited to submit a full proposal by the second submission deadline. This full proposal will be subject to a new, independent evaluation.

The PIC is a 9-digit number that serves as a unique identifier for organisations (legal entities) registered in the portal.

The EU Participant Register contains all participants in EU programmes. Any legal entity wishing to participate in a call for proposals/tender with eSubmission must be registered.

Partners are the signatories of the grant agreement and can claim project costs as part of regular reporting.

The Self-Registrant is the person who enters a new organisation into the Participant Register for the first time and manages the organisation's data until a LEAR is appointed.

A work package is a building block of the project work plan that enables project management to define the steps required to complete the work. A work package can be considered as a sub-project that, together with other work package units, forms the complete project.
