More　and　more　college　students　are　turning　to　Web　resources　for　gathering　information　fortheir　report　writing．　Many　of　them，　however，　use　websites　inefficiently　and　seem　unaware　oftheir　limitations．　Existing　Website　evaluation　tools　show　lack　of　effectiveness．　Furthermore，　atpresent　there　are　only　a　few　website　evaluation　tools　developed　in　Japan．　　　The　purpose　of　this　study　is　to　introduce　the　process　of　making　an　evaluation　scale　forwebsites　as　information　resources，　and　to　examine　the　effectiveness　of　the　scale．　A　literaturereview　of　previous　studies　has　made　it　clear　that　evaluation　criteria　for　websites　have　two　maindimensions．　They　are：　（1）　information　reliability　and　（2）　accessibility　to　information．　Theformer　dimension　consists　of　five　sub－dimensions：　authority，　accuracy／objectivity，　coverage，currency／stability，　and　purpose／audience．　For　each　of　the　five　sub－dimensions　and　the　secondmain　dimension，　twenty　evaluation　items　were　chosen．　A　20－item／6－point　Likert－scale　Websiteevaluation　scale　was　then　created．　　　Effectiveness　of　the　Website　scale　was　examined　using　two　experiments．　ln　the　firstexperiment，　subjects　were　110　Japanese　college　students　and　5　specialists．　The　subjectsassessed　two　kinds　of　Websites　by　using　the　scale．　The　two　Websites　were　deliberately　createdso　that　their　quality　differed，　one　of　a　higher　quality，　and　the　other，　a　lower　quality．　The　resultsof　the　experiment　have　shown　the　scale　to　possess　a　high　level　of　stability，　and　that　individual differences　did　not　have　significant　effect　in　Website　evaluation．　The　Website　scale　was　foundto　be　easy－to－use　and　suitable　for　most　users．　　In　the　second　experiment，　subjects　used　in　the　experiments　were　91　Japanese　collegestudents．　The　subjects　went　over　the　60　items　in　the　checklist　for　Website　evaluation　beforeand　after　assessing　the　Website　using　the　Website　scale．　The　results　of　the　checklist　takenbefore　and　after　the　evaluation　of　website　were　compared．　The　result　also　suggests　that　thestudent’s　consciousness　in　Website　evaluation　has　risen，　and　essential　skill　in　evaluatingwebsites　as　information　resources　was　acquired　by　using　the　Website　scale．　　These　findings　have　indicated　that　the　Website　scale　is　indeed　an　effective　tool　for　personswho　use　websites　as　information　resources．
