Chapter One — 1.1 Background to the Study

In recent years, Sign Language Instruction has emerged as a critical factor shaping academic performance of learners with special needs across organizations operating in and around Selected Listed Manufacturing Firms in Nigeria. As institutions grapple with the pressures of globalization, regulatory reform, and shifting stakeholder expectations, understanding how sign language instruction relates to academic performance of learners with special needs has become an important area of both scholarly and practical concern.

Selected Listed Manufacturing Firms in Nigeria presents a useful setting for examining this relationship precisely because the conditions there — structural, regulatory, and behavioural — differ from those typically assumed in the broader literature, most of which draws on evidence from more developed economies.

1.2 Statement of the Problem

Despite a growing body of literature on sign language instruction, there remains limited consensus on the precise nature of its relationship with academic performance of learners with special needs, particularly within Selected Listed Manufacturing Firms in Nigeria. Many organizations continue to make decisions about sign language instruction without a clear, evidence-based understanding of how those decisions ultimately affect academic performance of learners with special needs. This gap between practice and empirical understanding is the central problem this study seeks to address.
