Goleman EI is most commonly assessed via the EMOTIONAL AND SOCIAL COMPETENCY INVENTORY (ESCI, formerly ECI - Emotional Competence Inventory). ESCI HISTORY: developed by Goleman + Boyatzis + Hay/McBer (later Hay Group) starting late 1990s; ECI v1 + v2 published 2002 + 2007; rebranded ESCI in 2011 with refined competencies; Hay Group acquired by Korn Ferry 2015; current edition maintained + licensed by KORN FERRY HAY GROUP. INSTRUMENT DESIGN: 360-degree multi-rater + measures the 12 EI competencies (some versions 14-17 depending on edition) + ~68 items + raters include self + manager + peers + direct reports + others + 5-point frequency scale; typical administration via online platform; debrief by certified ESCI Accredited Practitioner. PSYCHOMETRIC PROPERTIES: published reliability + validity studies; ongoing academic + practitioner research; some academic critique (e.g. construct overlap with Big Five + critical-incident validation challenges). COPYRIGHT + LICENSING: ESCI is COPYRIGHTED + EXCLUSIVELY LICENSED through Korn Ferry Hay Group; individual + organizational licenses + accreditation required for administration; cost typically USD 150-500 per administration + accreditation training USD 5K-15K. ALTERNATIVE EI INSTRUMENTS: Bar-On EQ-i 2.0 (different EI model, separate); MSCEIT (Mayer-Salovey-Caruso) ability-based; TEIQue (Trait Emotional Intelligence Questionnaire); etc. - each commercially licensed + different in approach. NOTE ON COPYRIGHT: this rebuild describes the Goleman EI conceptual framework via publicly known publications + does NOT reproduce ESCI items + ratings + scoring procedures + norms which remain copyrighted Korn Ferry Hay Group property. ORGANIZATIONS using ESCI must purchase appropriate licenses; for purely conceptual development without ESCI assessment, the Goleman EI 4-domain + 12-competency + 6-style framework can be applied via public-domain materials.
