We present the Icelandic Standardization Benchmark Set: Spelling and Punctuation (IceStaBS:SP), a dataset designed to provide standardized text examples for Icelandic orthography. The dataset includes non-standard orthography examples and their standardized counterparts, along with detailed explanations based on official Icelandic spelling rules. IceStaBS:SP aims to support the development and evaluation of automatic spell and grammar checkers, particularly in educational settings. We evaluate various spell and grammar checkers using IceStaBS:SP, demonstrating its utility as a benchmarking tool and highlighting areas for future improvement.
