Many intervention studies of summer programmes examine their impact on employment and education outcomes, however there is growing interest in their effect on young people's offending outcomes. Evidence on summer employment programmes shows promise on this but has not yet been synthesised. This report fills this evidence gap through a systematic review and meta-analysis, covering summer education and summer employment programmes as their contexts and mechanisms are often similar.
The objective is to provide evidence on the extent to which summer programmes impact the outcomes of disadvantaged or 'at risk' young people.
The review employs mixed methods: we synthesise quantitative information estimating the impact of summer programme allocation/participation across the outcome domains through meta-analysis using the random-effects model; and we synthesise qualitative information relating to contexts, features, mechanisms and implementation issues through thematic synthesis. Literature searches were largely conducted in January 2023. Databases searched include: Scopus; PsychInfo; ERIC; the YFF-EGM; EEF's and TASO's toolkits; RAND's summer programmes evidence review; key academic journals; and Google Scholar. The review employed PICOSS eligibility criteria: the was disadvantaged or 'at risk' young people aged 10-25; were either summer education or employment programmes; a valid group that did not experience a summer programme was required; studies had to estimate the summer programme's impact on violence and offending, education, employment, socio-emotional and/or health ; eligible were experimental and quasi-experimental; eligible were high-income countries. Other eligibility criteria included publication in English, between 2012 and 2022. Process/qualitative evaluations associated with eligible impact studies or of UK-based interventions were also included; the latter given the interests of the sponsors. We used standard methodological procedures expected by The Campbell Collaboration. The search identified 68 eligible studies; with 41 eligible for meta-analysis. Forty-nine studies evaluated 36 summer education programmes, and 19 studies evaluated six summer employment programmes. The number of participants within these studies ranged from less than 100 to nearly 300,000. The PICOSS criteria affects the external applicability of the body of evidence - allowances made regarding study design to prioritise evidence on UK-based interventions limits our ability to assess impact for some interventions. The risk of bias assessment categorised approximately 75% of the impact evaluations as low quality, due to attrition, losses to follow up, interventions having low take-up rates, or where allocation might introduce selection bias. As such, intention-to-treat analyses are prioritised. The quality assessment rated 93% of qualitative studies as low quality often due to not employing rigorous qualitative methodologies. These results highlight the need to improve the evidence.
The quantitative synthesis examined impact estimates across 34 outcomes, through meta-analysis (22) or in narrative form (12). We summarise below the findings where meta-analysis was possible, along with the researchers' judgement of the security of the findings (high, moderate or low). This was based on the number and study-design quality of studies evaluating the outcome; the consistency of findings; the similarity in specific outcome measures used; and any other specific issues which might affect our confidence in the summary findings.Below we summarise the findings from the meta-analyses conducted to assess the impact of allocation to/participation in summer education and employment programmes (findings in relation to other outcomes are also discussed in the main body, but due to the low number of studies evaluating these, meta-analysis was not performed). We only cover the pooled results for the two programme types where there are not clear differences in findings between summer education and summer employment programmes, so as to avoid potentially attributing any impact to both summer programme types when this is not the case. We list the outcome measure, the average effect size type (i.e., whether a standardised mean difference (SMD) or log odds ratio), which programme type the finding is in relation to and then the average effect size along with its 95% confidence interval and the interpretation of the finding, that is, whether there appears to be a significant impact and in which direction (positive or negative, clarifying instances where a negative impact is beneficial). In some instances there may be a discrepancy between the 95% confidence interval and whether we determine there to be a significant impact, which will be due to the specifics of the process for constructing the effect sizes used in the meta-analysis. We then list the statistic and the -value from the homogeneity test as indications of the presence of heterogeneity. As the sample size used in the analysis are often small and the homogeneity test is known to be under-powered with small sample sizes, it may not detect statistically significant heterogeneity when it is in fact present. As such, a 90% confidence level threshold should generally be used when interpreting this with regard to the meta-analyses below. The presence of effect size heterogeneity affects the extent to which the average effects size is applicable to all interventions of that summer programme type. We also provide an assessment of the relative confidence we have in the generalisability of the overall finding (low, moderate or high) - some of the overall findings are based on a small sample of studies, the studies evaluating the outcome may be of low quality, there may be wide variation in findings among the studies evaluating the outcome, or there may be specific aspects of the impact estimates included or the effect sizes constructed that affect the generalisability of the headline finding. These issues are detailed in full in the main body of the review. -Engagement with/participation in/enjoyment of education (SMD):∘Summer education programmes: +0.12 (+0.03, +0.20); positive impact; = 48.76%, = 0.10; moderate confidence.-Secondary education attendance (SMD):∘Summer education programmes: +0.26 (+0.08, +0.44); positive impact; = N/A; = N/A; low confidence.∘Summer employment programmes: +0.02 (-0.03, +0.07); no impact; = 69.98%; = 0.03; low confidence.-Passing tests (log OR):∘Summer education programmes: +0.41 (-0.13, +0.96); no impact; = 95.05%; = 0.00; low confidence.∘Summer employment programmes: +0.02 (+0.00, +0.04); positive impact; = 0.01%; = 0.33; low confidence.-Reading test scores (SMD):∘Summer education programmes: +0.01 (-0.04, +0.05); no impact; = 0.40%; = 0.48; high confidence.-English test scores (SMD):∘Summer education programmes: +0.07 (+0.00, +0.13); positive impact; = 27.17%; = 0.33; moderate confidence.∘Summer employment programmes: -0.03 (-0.05, -0.01); negative impact; = 0.00%; = 0.76; low confidence.-Mathematics test scores (SMD):∘All summer programmes: +0.09 (-0.06, +0.25); no impact; = 94.53%; = 0.00; high confidence.∘Summer education programmes: +0.14 (-0.09, +0.36); no impact; = 94.15%; = 0.00; moderate confidence.∘Summer employment programmes: +0.00 (-0.04, +0.05); no impact; = 0.04%; = 0.92; moderate confidence.-Overall test scores (SMD):∘Summer employment programmes: -0.01 (-0.08, +0.05); no impact; = 32.39%; = 0.20; high confidence.-All test scores (SMD):∘Summer education programmes: +0.14 (+0.00, +0.27); positive impact; = 91.07%; = 0.00; moderate confidence.∘Summer employment programmes: -0.01 (-0.04, +0.01); no impact; = 0.06%; = 0.73; high confidence.-Negative behavioural outcomes (log OR):∘Summer education programmes: -1.55 (-3.14, +0.03); negative impact; = N/A; = N/A; low confidence.∘Summer employment programmes: -0.07 (-0.33, +0.18); no impact; = 88.17%; = 0.00; moderate confidence.-Progression to HE (log OR):∘All summer programmes: +0.24 (-0.04, +0.52); no impact; = 97.37%; = 0.00; low confidence.∘Summer education programmes: +0.32 (-0.12, +0.76); no impact; = 96.58%; = 0.00; low confidence.∘Summer employment programmes: +0.10 (-0.07, +0.26); no impact; = 76.61%; = 0.02; moderate confidence.-Complete HE (log OR):∘Summer education programmes: +0.38 (+0.15, +0.62); positive impact; = 52.52%; = 0.06; high confidence.∘Summer employment programmes: +0.07 (-0.19, +0.33); no impact; = 70.54%; = 0.07; moderate confidence.-Entry to employment, short-term (log OR):∘Summer employment programmes: -0.19 (-0.45, +0.08); no impact; = 87.81%; = 0.00; low confidence.∘Entry to employment, full period (log OR)∘Summer employment programmes: -0.15 (-0.35, +0.05); no impact; = 78.88%; = 0.00; low confidence.-Likelihood of having a criminal justice outcome (log OR):∘Summer employment programmes: -0.05 (-0.15, +0.05); no impact; = 0.00%; = 0.76; low confidence.-Likelihood of having a drug-related criminal justice outcome (log OR):∘Summer employment programmes: +0.16 (-0.57, +0.89); no impact; = 65.97%; = 0.09; low confidence.-Likelihood of having a violence-related criminal justice outcome (log OR):∘Summer employment programmes: +0.03 (-0.02, +0.08); no impact; = 0.00%; = 0.22; moderate confidence.-Likelihood of having a property-related criminal justice outcome (log OR):∘Summer employment programmes: +0.09 (-0.17, +0.34); no impact; = 45.01%; = 0.18; low confidence.-Number of criminal justice outcomes, during programme (SMD):∘Summer employment programmes: -0.01 (-0.03, +0.00); no impact; = 2.17%; = 0.31; low confidence.-Number of criminal justice outcomes, post-programme (SMD):∘Summer employment programmes: -0.01 (-0.03, +0.00); no impact; = 23.57%; = 0.37; low confidence.-Number of drug-related criminal justice outcomes, post-programme (SMD):∘Summer employment programmes: -0.01 (-0.06, +0.06); no impact; = 55.19%; = 0.14; moderate confidence.-Number of violence-related criminal justice outcomes, post-programme (SMD):∘Summer employment programmes: -0.02 (-0.08, +0.03); no impact; = 44.48%; = 0.18; low confidence.-Number of property-related criminal justice outcomes, post-programme (SMD):∘Summer employment programmes: -0.02 (-0.10, +0.05); no impact; = 64.93%; = 0.09; low confidence. We re-express instances of significant impact by programme type where we have moderate or high confidence in the security of findings by translating this to a form used by one of the studies, to aid understanding of the findings. Allocation to a summer education programme results in approximately 60% of individuals moving from never reading for fun to doing so once or twice a month (engagement in/participation in/enjoyment of education), and an increase in the English Grade Point Average of 0.08. Participation in a summer education programme results in an increase in overall Grade Point Average of 0.14 and increases the likelihood of completing higher education by 1.5 times. Signs are positive for the effectiveness of summer education programmes in achieving some of the education outcomes considered (particularly on test scores (when pooled across types), completion of higher education and STEM-related higher education outcomes), but the evidence on which overall findings are based is often weak. Summer employment programmes appear to have a limited impact on employment outcomes, if anything, a negative impact on the likelihood of entering employment outside of employment related to the programme. The evidence base for impacts of summer employment programmes on young people's violence and offending type outcomes is currently limited - where impact is detected this largely results in substantial reductions in criminal justice outcomes, but the variation in findings across and within studies affects our ability to make any overarching assertions with confidence. In understanding the effectiveness of summer programmes, the order of outcomes also requires consideration - entries into education from a summer employment programme might be beneficial if this leads towards better quality employment in the future and a reduced propensity of criminal justice outcomes.
Various shared features among different summer education programmes emerged from the review, allowing us to cluster specific types of these interventions which then aided the structuring of the thematic synthesis. The three distinct clusters for summer education programmes were: catch-up programmes addressing attainment gaps, raising aspirations programmes inspiring young people to pursue the next stage of their education or career, and transition support programmes facilitating smooth transitions between educational levels. Depending on their aim, summer education programme tend to provide a combination of: additional instruction on core subjects (e.g., English, mathematics); academic classes including to enhance specialist subject knowledge (e.g., STEM-related); homework help; coaching and mentoring; arts and recreation electives; and social and enrichment activities. Summer employment programmes provide paid work placements or subsidised jobs typically in entry-level roles mostly in the third and public sectors, with some summer employment programmes also providing placements in the private sector. They usually include components of pre-work training and employability skills, coaching and mentoring. There are a number of mechanisms which act as facilitators or barriers to engagement in summer programmes. These include tailoring the summer programme to each young person and individualised attention; the presence of well-prepared staff who provide effective academic/workplace and socio-emotional support; incentives of a monetary (e.g., stipends and wages) or non-monetary (e.g., free transport and meals) nature; recruitment strategies, which are effective at identifying, targeting and engaging participants who can most benefit from the intervention; partnerships, with key actors who can help facilitate referrals and recruitment, such as schools, community action and workforce development agencies; format, including providing social activities and opportunities to support the formation of connections with peers; integration into the workplace, through pre-placement engagement, such as through orientation days, pre-work skills training, job fairs, and interactions with employers ahead of the beginning of the summer programme; and skill acquisition, such as improvements in social skills. In terms of the causal processes which lead from engagement in a summer programme to outcomes, these include: skill acquisition, including academic, social, emotional, and life skills; positive relationships with peers, including with older students as mentors in summer education programmes; personalised and positive relationships with staff; location, including accessibility and creating familiar environments; creating connections between the summer education programme and the students' learning at home to maintain continuity and reinforce learning; and providing purposeful and meaningful work through summer employment programmes (potentially facilitated through the provision of financial and/or non-financial incentives), which makes participants more likely to see the importance of education in achieving their life goals and this leads to raised aspirations. It is important to note that no single element of a summer programme can be identified as generating the causal process for impact, and impact results rather from a combination of elements. Finally, we investigated strengths and weaknesses in summer programmes at both the design and implementation stages. In summer education programmes, design strengths include interactive and alternative learning modes; iterative and progressive content building; incorporating confidence building activities; careful lesson planning; and teacher support which is tailored to each student. Design weaknesses include insufficient funding or poor funding governance (e.g., delays to funding); limited reach of the target population; and inadequate allocation of teacher and pupil groups (i.e., misalignment between the education stage of the pupils and the content taught by staff). Implementation strengths include clear programme delivery guidance and good governance; high quality academic instruction; mentoring support; and strong partnerships. Implementation weaknesses include insufficient planning and lead in time; recruitment challenges; and variability in teaching quality. In summer employment programmes, design strengths include use of employer orientation materials and supervisor handbooks; careful consideration of programme staff roles; a wide range of job opportunities; and building a network of engaged employers. Design weaknesses are uncertainty over funding and budget agreements; variation in delivery and quality of training between providers; challenges in recruitment of employers; and caseload size and management. Implementation strengths include effective job matching; supportive relationships with supervisors; pre-work training; and mitigating attrition (e.g., striving to increase take up of the intervention among the treatment group). Implementation weaknesses are insufficient monitors for the number of participants, and challenges around employer availability.
许多关于暑期项目的干预研究考察了其对就业和教育成果的影响,然而,人们越来越关注这些项目对年轻人犯罪结果的影响。关于暑期就业项目的证据显示了这方面的前景,但尚未进行综合分析。本报告通过系统综述和荟萃分析填补了这一证据空白,涵盖暑期教育和暑期就业项目,因为它们的背景和机制通常相似。
目标是提供证据,证明暑期项目对弱势或 “有风险” 的年轻人的成果产生影响的程度。
本综述采用混合方法:我们通过使用随机效应模型的荟萃分析,综合定量信息,估计暑期项目分配/参与在各个成果领域的影响;我们通过主题综合,综合与背景、特征、机制和实施问题相关的定性信息。文献检索主要在2023年1月进行。检索的数据库包括:Scopus;PsychInfo;ERIC;青年就业与成长基金(YFF-EGM);教育捐赠基金会(EEF)和青少年犯罪问题行动组织(TASO)的工具包;兰德公司的暑期项目证据综述;主要学术期刊;以及谷歌学术。本综述采用PICOSS纳入标准:参与者为10至25岁的弱势或 “有风险” 的年轻人;项目为暑期教育或就业项目;需要一个未参加暑期项目的有效对照组;研究必须估计暑期项目对暴力犯罪、教育、就业、社会情感和/或健康的影响;纳入的研究为实验性和准实验性研究;纳入的研究来自高收入国家。其他纳入标准包括在2012年至2022年期间以英文发表。与符合条件的影响研究相关的过程/定性评估或英国干预措施的评估也包括在内;考虑到赞助商的兴趣,纳入了后者。我们使用了坎贝尔合作组织期望的标准方法程序。检索确定了68项符合条件的研究;其中41项符合荟萃分析的条件。49项研究评估了36个暑期教育项目,19项研究评估了6个暑期就业项目。这些研究中的参与者人数从不到100人到近30万人不等。PICOSS标准影响了证据主体的外部适用性——在研究设计方面对基于英国的干预措施的证据进行优先考虑,这限制了我们评估某些干预措施影响的能力。由于失访、随访损失、干预措施的接受率低或分配可能引入选择偏差,约75% 的影响评估被归类为低质量。因此,优先进行意向性分析。质量评估将93% 的定性研究评为低质量,通常是由于未采用严格的定性方法。这些结果凸显了改进证据的必要性。
定量综合分析通过荟萃分析(22项)或叙述形式(12项),考察了34项成果的影响估计值。我们在下面总结了可以进行荟萃分析的结果,以及研究人员对结果可靠性的判断(高、中或低)。这是基于评估该成果的研究数量和研究设计质量、结果的一致性、所使用的具体结果测量方法的相似性,以及可能影响我们对汇总结果信心的任何其他具体问题。下面我们总结了为评估分配到/参与暑期教育和就业项目的影响而进行的荟萃分析的结果(与其他结果相关的发现也在正文讨论,但由于评估这些结果的研究数量较少,未进行荟萃分析)。我们只涵盖两种项目类型的汇总结果,即暑期教育和暑期就业项目的结果没有明显差异的情况,以避免在并非如此的情况下将任何影响归因于两种暑期项目类型。我们列出结果测量指标、平均效应量类型(即标准化平均差(SMD)或对数优势比)、该发现所涉及的项目类型,然后是平均效应量及其95% 置信区间以及对结果的解释,即是否似乎存在显著影响以及影响方向(正或负,明确负面影响有益的情况)。在某些情况下,95% 置信区间与我们确定是否存在显著影响之间可能存在差异,这将归因于荟萃分析中构建效应量过程的具体情况。然后,我们列出异质性检验的卡方统计量和p值,以表明异质性的存在。由于分析中使用的样本量通常较小,并且已知小样本量的情况下异质性检验的功效不足,因此在实际存在异质性时可能无法检测到统计学上显著的异质性。因此,在解释下面的荟萃分析时,通常应使用90% 的置信水平阈值。效应量异质性的存在会影响平均效应量适用于该暑期项目类型所有干预措施的程度。我们还对我们对总体结果可推广性的相对信心进行了评估(低、中或高)——一些总体结果基于少量研究样本;评估该结果的研究可能质量较低;评估该结果的研究之间的结果可能存在很大差异;或者所包括的影响估计或构建的效应量的具体方面可能会影响总体结果的可推广性。这些问题在综述正文中有详细阐述。
