at Berkeley,was pre-vailed upon to undertake the re-organizntion of the Los AngelesPolice Department.Chief Vollmer's initia plan included a surveyof the three important factors of the situntion;namely,(1)phy-sical equipment including buildings,ete,(2)personnel includingthe quantity and quality of the man power of the department and  \n(3)the crime situation faced,ineluding place,time nature ete.of.offenses which had to be handled by this department.  \nThis survey which was planned and carried out in a scientifiemanner became the basis for recommendations to the City Councilfor necessary changes in the directions mentioned.  \nThe present study was started at Chief Vollmer's request,to as-sist in the survey of personnel.The report includes rcsults of workdone first under Mr.Vollmer's administration and later continuedunder the administration of Chief Lee Heath.  \nIn the course of the investigation tests were given to the follow-ing groups:  \na.1712 men comprising the entire Police Department in 1923.  \nb.824 students at the Police School.  \n(This school was crented as part of the re-organization pro-gramme of Mr.Vollmer and was conducted by Captain Fin-linson.)  \ne.625 Civil Service applicants for entrance to the Police School.(The Police Department requested of Civil Service that testsbe made a requirement for entrance to the Police School.  \nd.1760 students entering the University ofCalifornia,SouthernBranch in Scptember 1923.  \n(252)  \n## I.ORIGINAL SURVEY OF 1923\n\nAt Mr.Vollmer's request,1712 men comprising the entire policeforce were given an intelligence test.This test was conducted bythe writers at the University of California,Southern Branch.  \nEach man was given two forms of the Army Alpha Test.Laterthe Terman Group and National Intelligence Tests were given toevery man whose score was less than fifty on the second ArmyAlpha Test.  \nRESULTS OF 1923 SURVEY OF POLICE PERSONNEL.  \n## A.Discussion of distribution of seores of total groupTable 1 shows the distribution of scores of total police force\n\n1.The total range is very wide showing a group practically un-selected.The range on the first test includes scores from 3 to 2C1and on the second test from 6 to 198.The mean on the second testis 102.The probable error of the distribution on Test IIis 25 pointsindicating that approximately 50 per cent of the cases lie betwenthe score 77 and 127.**  \n2.The results show that,according to the first test,73 per zercscore less than B;on the second test 55 per cent score less than B.  \n3.The correlation(Pearson product-moment)between the scoreon the first Alpha and the score on the second Alpha is very high,÷96.The individualvariability inscore on first and score on secondLest ranges from—35 points to+66 points with a mean variation of+17.8.This shows that even with this high correlation the ralia-bility for individual diagnosis,in certain cases,might be questionqd.  \nIn cases in
