The eliability of the Boehm 3 was detemied by checkig iteal cosistecy, stadad eo of measuemet, test-etest eliability, ad alteate foms eliability.

A test ca be said to have evidece of validity if it measues what it states that it measues. The Boehm 3 cotais evidece of validity based o test cotet ad elatios to othe vaiables. Reseach outlied i the Boehm 3 Examie s Maual suppots the claim that a child s ability to make elatioal judgmets usig the Boehm-3 cocept tems, plus thei syoyms ad atoyms, is basic to udestadig classoom istuctio, whethe i the fom of followig teache diectios, completig cuicula tasks.

The coelatio betwee Boehm 3 ad Boehm R aged fom.61 to.96. It is impotat to ote that while both the Boehm 3 ad its pedecesso test 50 basic cocepts, ew cocepts have bee added to Boehm 3. Secodly, a study was coducted to look at the elatioship betwee Boehm 3 ad the Metopolita Achievemet Tests, Eighth Editio ( Educatioal Measuemet, Stadadizatio Editio 1999), a test used to assess studet achievemet i the aeas of souds ad pit (emeget liteacy skills), Atemate Foms Reliability Mea SD Spig 813.00 2.16 829.00.83 1.62 706.00.82 1.14 748.00.88 2.12 731.00 1.63 717.00.91 1.16 paticipatig i the Boehm 3 alteate foms study had a diffeece of 4 o fewe aw scoe poits fom oe fom to the othe.

A thid study ivolved a goup of 75 kidegate studets who wee admiisteed the Metopolita Readiess Test, Sixth Editio (Nuss & McGuava, 1995). This test evaluates the ealy skills equied i emeget eadig ad math. The coelatio betwee this test ad Boehm-3 aged fom.48 to.63. The coelatio betwee Boehm 3 ad the Otis-Leo School Ability Test, Seveth Editio (Otis & Leo, 1996) aged fom.45 to.68. The OLSAT 7 is used to measue thikig ad easoig by checkig studet pefomace o tasks. The modeate coelatio ca be expected due to the vaied cotet of the umeous aeas assessed with the OLSAT 7, suggestig that kowledge of basic cocepts is stogly elated to studet pefomace ad is a essetial compoet of thikig ad easoig. This futhe demostates the eed to make sue studets kow basic cocepts pio to admiisteig tests. The fial study was a Logitudial Study to Spig. A goup of 273 kidegate studets took pat i a compaiso of thei pefomace i the fall with thei pefomace i the spig o Boehm 3. The coelatio fo both Foms E ad F is.78, idicatig that studets who did well i the fall also did well i the spig.
