Block rating is number typically appearing on items that improves your chance to block an attack. Some abilities, enchantments, items and spells can contribute bonus block rating also (the bonus spell usually has the name "Improved Blocking" or "Increased Block X").
Block rating is not to be confused with "block value" which — prior to the Cataclysm Cataclysm expansion — increased the amount blocked (damage mitigation) each time a block occured, rather than affect the chance for a block to occur.
