Children who stutter (CWS) are placed at risk for being teased and bullied in Primary school (Blood \& Blood, 2004; Blood, Boyle, Blood \& Nalesnik, 2010; Evans, Healy, Kawai \& Rowland, 2008; Langevin, Kleitman, Packman \& Onslow, 2009) due to negative peer attitudes and perceptions (Blood \& Blood, 2004; Blood et al., 2010; Evans at al., 2008; Langevin et al., 2009). Negative attitudes and interactions result in CWS being viewed as different or disabled leading to social rejection (Evans et al., 2008). Social rejection may lead to long term negative consequences such as reduced academic and social interactions, depression, and negative self-perceptions (Ferguson, Miguel, Kilburn \& Sanchez, 2007; Hawker \& Boulton, 2000) and are harmful if not urgently addressed. This is prevalent in the adolescent population due to stress and rapid changes of emotion at this age (Evans et al, 2008). Attitudes and perceptions overlap (Foster, 2006) which is useful as negative peer attitudes may lead to negative perceptions towards CWS (Blood \& Blood, 2004; Blood et al., 2010; Evans et al., 2008; Langevin et al., 2009). While the relationships between attitudes, attitude change and behaviour change are complex and multifaceted (Prochaska, Redding \& Evers 2008), this study focusseson f attitude as the precursor for change. (Scott, 2000). This study does not focus on behaviour change. Attitudes are described as an individual's evaluation of issues, objects and other individuals. The evaluation of another person or object can be positive or negative (Petty, Wegener \& Tormala, 2003) Furthermore, attitude formation is known to continuously change over time, (Krahe \& Altwasser, 2006) as it is learnt and shaped (Foster, 2006).
The International Classification and Functioning of Disability (ICF) framework (Murphy, Yaruss \& Quesal., 2007) considers holistic management of the CWS. It advocates for classroom-based interventions to reduce teasing and bullying (Merrell, Gueldner , Ross \& Isava., 2008; Murphy et al., 2007; Langevin, 2009) because children spend a large amount of time with teachers (Blank et al, 2009). Classroom-based interventions also empowers teachers. International public education addresses stuttering-related stigma (Scott, 2000) through reducing the debilitating nature of stuttering and improving social environments and reactions (St Louis, 2011). These publicised campaigns have not documented effectiveness. However, the potential for classroom-based interventions to change attitudes to stuttering are emerging. Survey of Human Attributes- Stuttering (POSHA-S) showed that negative attitudes are prevalent in school-aged children (Flynn \& St Louis, 2011) A follow-up study conducted in South Africa, using the POSHA-S, showed that teachers were requesting assistance with managing negative attitudes to stuttering (Abrahams, 2015). The Teasing and Bullying: Unacceptable Behaviour (TAB) included teacher administered activities and yielded positive results pre- and post- intervention (; Langevin, 2009; Langevin \& Prasad, 2012). The TAB was however not suitable for South African classrooms due to time and technology constraints as well as contextual, cultural and linguistic differences. This led to the development of the South African specific intervention, the CCR intervention. It was developed and has been refined since 2009 as part of a series of the University of Cape Town projects. The CCR intervention yielded positive results at 1 month post-intervention within the lower and higher quintile population respectively (Kathard et al.,2014 \& Walters, 2015) and more so at 6 months post-intervention (Badroodien, 2015). The feasibility study thus reported potential effectiveness of the CCR intervention at 1 and 6 months post-intervention (Badroodien, 2015). The findings were however inconclusive as it called for a more rigorous design method. The findings also reported that a RCT was feasible despite concerns regarding the retention of participants. A RCT was thus recommended as the next stage in these projects (Badroodien, 2015) The CCR intervention addresses prosocial behaviours and skills, including but not limited to the promotion of positive behaviour change, peer support and resilience through intervention (Blank et al, 2009) in the areas of Positive Social Distance (PSD), Verbal Interaction (VI) and Social Pressure (SP) in the CCR intervention. The areas of PSD, VI and SP are additionally measured where PSD represents the overall ease, acceptance of and comfort a child feels when around CWS (Langevin, 2009; e.g. 'I would let a child who stutters hang out with us'). VI evaluates peer's negative thoughts, emotions and feelings, e.g. frustration experienced towards a CWS (Langevin et al., 2009). SP evaluates general thoughts regarding CWS through examining social pressure and subjective norms (Langevin, 2009). An example is 'I would be ashamed to be seen with a child who stutters'. The promotion of these prosocial behaviours and skills may facilitate the prevention of anxiety and depression (Blank et al, 2009). In post-apartheid schools are unequal particularly in relation to resources. IN an attempt to address such inequality, a system based on the National Norms and Standards for school funding policy was developed to classify schools in relation to resources..) . (Motala, 2006) using the National Norms and Standards for School Funding (NNSSF) policy (Mestry \& Ndhlovu, 2014). Lower quintiles one, two and three are no fee paying schools (Department of Education, 2009; Sayed \& Motala, 2012).Higher quintiles four and five are fee-paying schools that are better resourced (Department of Education, 2009; Sayed \& Motala, 2012). This study therefore aims to compare the treatment effect in the low and high quintiles, explored as a subgroup in this study
