This study assessed validity and reliability of the Health Knowledge Inventory‐Alpha (HKI‐Alpha) in a sample of high school seniors. The HKI‐Alpha, a general health knowledge test, consists of 110 multiple choice items covering 11 health content areas. All seniors attending one of four high schools completed HKI‐Alpha twice, one week apart. A secondary sample of college students also was tested. Descriptive analysis revealed the test discriminated among examinees and avoided ceiling and floor effects. Test‐retest reliability was .81 (n = 355). Internal consistency reliability (KR20) was .85 (n = 418). A sample of college students scored significantly higher than the high school students, demonstrating construct validity. Other estimates of content validity, criterion‐related validity, and construct validity were high. (J Sch Health. 1991;61(10):430–432)
