Here is an a WCS calculations chart from 2001, things have likely changed a bit since then but I think it can give you a rough idea of how they calculate it:
WHOLE CANDIDATE SCORE (WCS)
WCS: (6 x CEER) + (3 x CLS) + (PAE SCORE)
COLLEGE ENTRANCE EQUIVALENCE SCORE (SCHOLASTIC APTITUDE TEST, “SAT”)
CEER: (.364 x HSR) + (.269 x SATV) + (.432 x SATM) - 48
COLLEGE ENTRANCE EQUIVALENCE SCORE (AMERICAN COLLEGE TEST, “ACT”)
ACEER: (.219 x HSR) + (9.43 x ACTM) + (4.62 x ACTE) + (0.45 x ACTS) + (4.01 x ACTR) - 41.5
HIGH SCHOOL RANK (HSR)
HSR: ((2 x HS·STANDING) -1) / (2 x CLASS SIZE);
*HSR TABLE REQUIRED TO CONVERT CALCULATED RESULT TO HSR SCORE
COMMUNITY LEADER SCORE (CLS)
CLS: (EX+ AT+ FAS) / 3

FACULTY APPRAISAL SCORE (FAS): The average of the candidate's scores on the
School Official Evaluation (SOE) of Candidate Forms (DD Form 1869) on a scale of 40
740.
NOTE: The information above contains general guidance on the components used to
compute a Community Leader Score (CLS). In a process as imprecise as leadership
assessment, subjective judgment must be applied to the evaluation process in order to
take into consideration special situations: e.g., an unusually high or low Faculty Appraisal
Score (FAS) that is inconsistent with other elements of the candidate record; athletic
achievement in an extremely large or small school or an excellent or marginal program;
an activity record that may not fit the categorizations of the Candidate Activities Record.
The Admissions Office and the Admissions Committee are expected to make
adjustments in the components of the CLS to take into account such situations.
