VOCAB?ULARY? LIST Preli?minar?y Engli?sh Test (PET) Intro?ducti?on to the PET Vocab?ulary? List The PET Vocab?ulary? List gives? teach?ers a guide? to the vocab?ulary? neede?d when prepa?ring stude?nts for the PET exami?natio?n. Backg?round? to the List The PET list was origi?nally? devel?oped by Cambr?idge ESOL in consu?ltati?on with exter?nal consu?ltant?s to guide? item write?rs who produ?ce mater?ials for the PET exami?natio?n. It inclu?des vocab?ulary? from the Counc?il of Europ?e’s Thres?hold (1990) speci?ficat?ion and other? vocab?ulary? which? corpu?s evide?nce shows? is high-frequ?ency. The list cover?s vocab?ulary? appro?priat?e to this level? of Engli?sh and inclu?des recep?tive vocab?ulary? (words? that the candi?date is expec?ted to under?stand? but which? is not the focus? of a quest?ion), and produ?ctive? vocab?ulary? (words? that the candi?date needs? to know to answe?r a quest?ion). The list does not provi?de an exhau?stive? list of all words? which? appea?r on the PET quest?ion paper?s and candi?dates? shoul?d not confi?ne their? study? of vocab?ulary? to the list alone?.

In order? to maint?ain its curre?ncy, the PET list is updat?ed on an annua?l basis? by the addit?ion and remov?al of words?, using? a corpu?s-based? appro?ach. Sugge?sted addit?ions to the wordl?ist are colla?ted and the frequ?ency of these? words? is obtai?ned by refer?ence to estab?lishe?d corpo?ra (elect?ronic? datab?ases). The corpo?ra in quest?ion repre?sent recep?tive and produ?ctive? langu?age in gener?al conte?xts. The main corpo?ra used for the valid?ation? of the PET Vocab?ulary? List are: ? the Cambr?idge Learn?er Corpu?s (CLC) which? inclu?des over 20 milli?on words? of writt?en learn?er Engli?sh at six level?s; ? the Briti?sh Natio?nal Corpu?s (BNC) which? inclu?des 100 milli?on words? of writt?en and spoke?n nativ?e sp
