Research to practice: Applying risk/needs assessment to offender classification
Effective classification is critical for the success of any correctional agency. With shrinking financial resources for government, increased scrutiny of correctional practices and greater demands for public safety, the process of making decisions about offender placement, treatment and release becomes even more important.
An offender classification system is only as good as the tools used to make the classification decisions. Moreover, the validity of the tools must be established in terms of the classification decisions to which the tools are applied, not some other interesting, but irrelevant, criteria such as diagnosis or underlying personality constructs.2
Postsentence correctional classification is undertaken to help correctional practitioners make decisions about their clientele in four basic areas: the institutional security level for the offender during incarceration, the release of an offender to the community via such mechanisms as parole or temporary absence, the amount of supervision that is appropriate in the community and the referral of an offender to work, academic, program or treatment options. The ultimate goal is to maximize public and institutional safety and to minimize the offender's illegal or otherwise antisocial behaviour in prison and in the community. To achieve both these goals in the most cost-effective manner, it is important for any offender classification system to focus on the risks, needs and responsivity of its clientele.3
Ontario has had considerable experience with the use of risk/needs assessment in its classification process, beginning in the early 1980s with the Level of Supervision Inventory (LSI).4 The LSI is a checklist of 53 items that are scored in binary, or 0-1, format by a trained assessor after conducting an intensive interview with the offender, reviewing all documentation and records of the client, and completing a number of collateral contacts to verify the assessor's earlier findings.
The LSI has been the subject of numerous studies in institutions,5 halfway houses6 and the community.7 It has been shown to be reliable and predictive of possible offender recidivism.8 It has also displayed an important dynamic validity component, predicting appropriately the changes in recidivism as criminogenic needs are increased or decreased.9 This characteristic sets the LSI apart from many of the earlier tools that focused primarily or exclusively on static historical facts, such as the Statistical Information on Recidivism (SIR) Scale.10
Although tools focused on static historical facts may be easier to score, it is our view that instruments based totally on the offender's past are less helpful to correctional administrators for two main reasons. First, they neglect many of the present circumstances of an offender, which are also relevant to reoffending,11 thus limiting their ultimate predictive utility. Second, they provide no instruction or direction for the type of management and treatment of an offender which is most likely to bring about positive change, therefore limiting their capacity to help staff lower an offender's degree of risk.12
Introducing the LSI-ORAfter 15 years' experience with the LSI in the community with probationers and parolees, Ontario decided to update it and expand its use to all offenders under its mandate. The Level of Service Inventory - Ontario Revision (LSI-OR), as it is now called, is a required assessment for all adult inmates undergoing any institutional classification or release decision, for all young offenders both in secure and open custody and for all probationers and parolees. The LSI-OR is readministered every six months and for any subsequent client-related decision.
Initiated in January 1996, this new policy for the LSI-OR is helping the Ministry unify its correctional practice. The policy contributes to increased continuity of care because all staff members are now using a common instrument, working from a common theoretical rationale and basing decisions on a common empirical database in the management, treatment and supervision of their offenders.
To get to this position, however, a large-scale training exercise was required. Designed by Don Andrews, in consultation with ministry resource people from the field, staff training and policy divisions, a series of intensive, two-day training sessions was provided to more than 800 employees.
Although the LSI-OR has maintained the same general format, data collection procedures and scoring system as the LSI, it differs from its predecessor in a number of important ways. Don Andrews worked with a team of ministry staff to decide on the innovations and to design the new test protocol.
Modifications were made only after a review of the risk assessment literature and the meta-analytic studies of the last decade.13
A reanalysis of data on the LSI items and extensive consultations with representatives of the many stakeholders in the process (correctional managers, probation officers, prison staff, professional associations, parole board members and staff, support staff and policy makers) was also done. Eight major changes were made to the tool.
The LSI-OR also includes a number of supplementary pages for text related to offence information, case notes and discharge summaries, as well as sections for administrative decision making and sign off. Again, these in-house, ministry-specific administrative sections were introduced to maximize the connection between the offender's risk/needs assessment, the practitioner's case management and the administrator's decision making.
Ontario's experience with the LSI-ORSummary data on the LSI-OR are routinely entered by field staff on the Ministry's Offender Management System (OMS), which was modified to include these data. Incorporating a risk/needs component into the offender database serves three principal functions. It allows the Ministry to monitor important client characteristics so programming and facilities can be designed to meet the needs of the clientele and, thereby, accommodate the characteristics of the offender population on more than just security. It also provides a relatively easy mechanism for continued research on the instrument. Finally, it allows system-wide establishment of quality assurance.
Earlier empirical research17 and recent field consultations revealed that the quality and accuracy of individual assessments can deteriorate with time and in the absence of continued training and supervision.
Following Colorado's example,18 where detailed examinations of large databases revealed a small, but bothersome incidence of scoring anomalies, the Ministry established a policy of flagging impossible or extremely unlikely scores or score combinations for further investigation, correction or clarification. Similarly, when aggregated data on a group of offenders from a specific location are inconsistent with the norms for that particular client group, the anomaly is brought to the attention of the local manager. The relationship between risk/needs assessment, case management, an empirical database and program design, evaluation and modification is illustrated schematically in Figure 1.
Figure 1
In the first nine months of implementation, LSI-OR data have been collected on more than 26,000 offenders. Some descriptive statistics are provided below. Sentenced inmates score considerably higher than probationers or parolees (see Figure 2). Young offenders score consistently higher than adults, regardless of gender or sentence type, and males tend to score higher than females (see Table 1). What is particularly interesting is that even though the distribution of scores differs for various offender groups, (especially inmates and probationers) the recidivism rates for any given score remain very similar, indicating that whether a given number of risk/needs items is present for an inmate or for a probationer, the likelihood of recidivism is virtually the same (see Figure 3).

Including more detailed information on the Ministry's OMS has also provided an opportunity to examine the use of the professional override. Initially, there was concern that the fear of underestimating a client's risk (making a "false negative" error) would far outweigh concern about overestimating a client's risk (making a "false positive" error) because of the vastly different consequences of each and the inherently cautious mindset these differences instill in correctional practitioners. To date, the use of the override has not been excessive, nor has it been applied more frequently to increase an offender's risk category.

Approximately 88.6% of the risk levels have been left unchanged. Use of the override was divided fairly evenly between decisions to classify upward by increasing the risk level (6.2%) and decisions to classify downward by lowering the risk level (5.1%). Most reclassifications were to the adjacent level of risk although some were over two-to-four levels, usually because certain ministry policies require automatic or administrative overrides. Current analyses are looking at whether the strengths and added concerns correlate with the override and, if so, which ones.
Users have been quite accepting of these changes to the original LSI. Probation and parole officers have been particularly encouraged by the changes that reflected their concerns. While hundreds of recommendations were recorded during the field consultations, and not all could be accommodated, many of the more popular themes, such as the specific risk/needs items, are found in the LSI-OR. Many suggestions contradicted each other, however. For example, some staff requested greater simplicity in the instrument, while others called for more details and a more comprehensive or complex tool.
At the institutional level, acceptance of the LSI-OR has been more varied, partly because it has a wider range of applications in the prison setting and partly because risk/needs assessment had not previously been part of the inmate classification process.
Because the LSI-OR has been linked with offender recidivism, however, its application to inmates in conjunction with parole, temporary absence and electronic monitoring programs has been received quite well by practitioners and the Ontario Board of Parole. Although administration of the LSI was not a routine requirement for these programs, it was often used by professional staff on a voluntary basis.
The administration of the LSI-OR as part of the inmate classification process has been greeted with some scepticism for a few reasons. Some staff confuse the concept of risk to reoffend with the security level of an institution, perhaps because both classification schemes have traditionally used the same terminology of "maximum," "medium" and "minimum." Second, inmates score higher on the LSI-OR in comparison to probationers (Table 1), resulting in a high percentage rated as high risk. This is sometimes automatically translated into maximum security.
When staff members come to this conclusion on a particular offender, they may decide that the assessment instrument is in error. However, such a view overlooks the twofold value of using the LSI-OR as part of the institutional classification process. First, it provides an index of the client's risk to reoffend, which in itself is important for any kind of community-based decision or activity. Equally important, it profiles the offender's criminogenic risks and needs, which should then be considered not just in terms of institutional placement but also in terms of assignment to the appropriate programs and services once the offender has been placed in a facility.
