The Complexity, Accuracy, and Fluency (CAF) framework is among the fundamental models in second language acquisition (SLA) research, providing a robust structure for analysing the multifaceted nature of language performance. This paper sets out to offer a comprehensive examination of the CAF model, emphasizing its critical role in evaluating the linguistic development of language learners. It thoroughly defines each component—complexity, accuracy, and fluency—while highlighting the intricate challenges involved in measuring these dimensions. Through a review of various empirical studies and methodological approaches, the paper presents a nuanced analysis of how these aspects of language performance are quantified and assessed within SLA research. This study critically evaluates the effectiveness of different metrics used to measure complexity, accuracy, and fluency. It also explores the broader implications of these measurements for understanding L2 proficiency and the cognitive processes underlying language production. Furthermore, the study identifies existing gaps in the literature and proposes future research directions aimed at enhancing the reliability and validity of CAF measurements. By providing an in-depth analysis of both the theoretical and practical applications of the CAF model, this paper contributes to a deeper understanding of L2 performance assessment. It underlines the importance of developing more refined and comprehensive approaches to measure these dimensions, with the ultimate goal of advancing SLA research and improving the effectiveness of language teaching methodologies.

Karmaşıklık, Hatasızlık ve Akıcılık (KHA) modeli, ikinci dil edinimi (SLA) araştırmalarındaki temel modeller arasında yer almakta ve dil performansının çok yönlü doğasını analiz etmek için sağlam bir çerçeve sunmaktadır. Bu çalışma; karmaşıklık, hatasızlık ve akıcılık modelinin, ikinci dil öğrenenlerin dil gelişimini değerlendirmedeki kritik rolünü vurgulayarak modelin kapsamlı bir incelemesini sunmayı amaçlamaktadır. Makale, modeldeki dilbilimsel karmaşıklık, hatasızlık ve akıcılık bileşenlerini süreç içerisinde gelişimlerine kısaca değinerek her bir bileşenin ayrıntılı bir tanımını sunmaktadır. İlgili alan yazında rapor edilen çeşitli deneysel çalışmaların ve metodolojik yaklaşımların gözden geçirildiği bu makalede, ayrıca, dil performansının dilbilimsel yönlerinin ikinci dil araştırmalarında nicel ve nitel yöntemlerle nasıl değerlendirildiğine dair bir analiz sunulmaktadır. Çalışmada karmaşıklık, hatasızlık ve akıcılığı ölçmek için kullanılan farklı metriklerin etkililiği eleştirel bir şekilde değerlendirilmektedir. Ayrıca, bu ölçümlerin ikinci dil yeterliliğini ve dil üretiminin altında yatan bilişsel süreçleri anlamaya yönelik daha geniş etkileri araştırılmaktadır. Son olarak, çalışma mevcut literatürdeki boşlukları belirlemekte ve karmaşıklık, hatasızlık ve akıcılık ölçümlerinin güvenilirliğini ve geçerliliğini artırmaya yönelik gelecekteki araştırma yönlerini özetlemektedir. KHA modelinin hem teorik hem de pratik uygulamalarını derinlemesine inceleyerek, bu makale ikinci dil performans değerlendirmesine dair daha derin bir içgörüye katkıda bulunmaktadır. Bu boyutların ölçülmesi için daha rafine ve kapsamlı yaklaşımlar geliştirilmesinin önemini vurgulayarak, ikinci dil araştırmalarının ilerlemesine ve dil öğretim metodolojilerinin etkinliğini artırmaya yönelik katkı sunmaktadır.
