Purpose: The current paper aims at the classification of Greek agronomists/extensionists in adult education philosophical frameworks; the exploration of frameworks' changes in the last 40 years; and the assessment of their relevance vis-à-vis the current developments. Design/Methodology/Approach: The research addressed a purposive sample of 30 agronomists divided into two groups (older-younger). Questionnaire-based survey was followed by a semi-structured interview. Findings: The views of both groups of agronomists follow the same orientation and revolve around the progressive and behaviourist philosophies. In terms of practice, the intervention of older agronomists mainly relates to the progressive, the liberal and the behaviourist philosophy while that of younger agronomists around the liberal framework; evidence shows a small turn of younger agronomists towards participatory extension. Practical Implications: The current piece of work puts forward the gaps and weaknesses of Extension in Greece both in terms of rhetoric and practice; notably, Greek agronomists do not seem capable to support bottom-up processes. Theoretical Implications: Research detected the espoused orientation of extensionists and the ways they assist their constituencies in practice. Originality/Value: The work reported here is considered one means of raising the awareness of the field's needs in documenting extensionists' educational philosophies and how they guide practice.
