Abstract
The California Policy Lab will evaluate the impact of the Santa Clara County Public Defender’s Office’s Pre-Arraignment Representation & Review Team (PARR) during the pilot implementation on pre-trial detention, release at arraignment, and case outcomes. The pilot will use a random process to assign legal staff to clients who are booked on felony charges and not released by a night judge within 24 hours of booking.

Experimental Details
Interventions
Intervention(s)
The Santa Clara Public Defender's Office created a Pre-Arraignment Representation & Review Team (PARR) that provided early public representation to individuals booked into the Santa Clara jail for the first 3 months of 2020 (prior to COVID-19). The PARR unit did not have sufficient resources to serve all individuals in custody pre-arraignment on felony charges in Santa Clara County. They therefore operated on a different day each week, intending to provide service to all eligible individuals booked in a specific period each week.

Primary Outcomes
Primary Outcomes (end points)
• The number of days detained pre-arraignment and pre-disposition
• Release at arraignment
• Charges filed (whether any charges are filed, number of charges filed, severity)
• Case dispositions (dismissals, charges being reduced)
Primary Outcomes (explanation)
Secondary Outcomes
Secondary Outcomes (end points)
• Motions to revoke probation
• Conviction
• Terms of sentences/sentence length when sentenced
• Average bail amount when money bail is set
Secondary Outcomes (explanation)
Experimental Design
Experimental Design
The PARR unit did not have sufficient resources to serve all individuals in custody pre-arraignment on felony charges in Santa Clara County. They therefore operated on a different day each week, intending to provide service to all eligible individuals booked in a specific period each week. Eligible individuals booked on a non-treatment day will make up the control group – if eligible for public defender services, their first interaction with the office is at arraignment.
Experimental Design Details
Not available
Randomization Method
The PARR team operated on a different day each week, each week serving individuals booked into custody during a specific time period. The team rotated through a 6-week schedule.

Experiment Characteristics
Sample size: planned number of clusters
N/A
Sample size: planned number of observations
We estimate that approximately 2,200 individuals were arrested in Santa Clara County during the PARR pilot period.
Sample size (or number of clusters) by treatment arms
Based on PARR’s weekly rotating schedule, we estimate services were offered to 17% of individuals (n~350) in custody post booking and pre-arraignment and that services were provided to approximately 1/3 of the individuals (n~125) to whom they were offered.
Minimum detectable effect size for main outcomes (accounting for sample design and clustering)
Based on these sample calculations, we expect an intent-to-treat (ITT) minimum detectable effect (MDE) on the main outcomes of interest of 5-7 percentage points (95% confidence; 80% power). Release at arraignment: population mean:0.14; MDE: 0.050 Release pre-disposition: population mean: 0.30; MDE: 0.066 Acquittal/dismissal rate: population mean: 0.11; MDE: 0.046 Felony conviction rate: population mean: 0.054; MDE: 0.072
