What we do

The mission of Mend the Gap is to close the achievement gap. We do this through automated and customized data visualizations and reports. It's very exciting because we get to help schools do more of what they do well (working with students and families) by automating the difficult process of processing data.

Our platform is fully customized to meet the needs of your school/district. We focus on your specific needs and then build beautiful and meaningful visualizations that give you the information that you need to support all of your students. For example, one of our partner schools in Santiago, Chile wanted to improve their attendance rates because they noticed that too many students were chronically absent. We built a visualization like the one you see below to uncover the why behind student absences.

Getting to the why and beyond the what is a key part of what makes Kimche such an important tool. The reality for schools is that they are always working very hard with limited resources, so having the capacity to dig deep into data intersections is one that is often unobtainable. We remove that barrier and give you direct access to your visual data and update it on a weekly basis so that you are constantly gaining new insights into the needs of your students.

Our flagship product is called Kimche. In the indigenous Mapuche culture of South America, Kimche means "wisdom." We wish to provide all educational stakeholders the wisdom that comes from making sense of big data and individualizing student supports. We have made tremendous progress in Chilean schools in the specific areas of attendance and retention and are ready to scale our efforts.

We have a great track record of positive results with our partner schools. We work with schools to identify areas of need and support and then design our visualizations and reports on those needs. Schools all use multiple data points from semi-annual benchmark assessments, anecdotal evidence, as well as academic performance, attendance, behavior, and health data. Schools often meet in teams to help navigate their way through these disparate data sources to better support the needs of individual students. Kimche by Mend the Gap serves as the solution between data collection and intervention.

Kimche has increased attendance rates throughout Chile and increased state subsidies to schools by millions of dollars! The state subsidy in Chile is directly connected to attendance so when attendance goes down so does the amount of funding for a school. This specific issue allowed us to customize Kimche to address attendance in schools, resulting in a year over year increase of attendance of 2.8% and a national subsidy increase of over $20,000,000!

We are unique in our commitment to solving problems and customizing our solutions to the needs of individual customers and that approach has proven successful. Our approach is always to support each individual student and we do that by giving schools access to important student information in easy to understand and easy to use visualizations.

Our visualizations help schools look at historic data to optimize plans for the future. Seeing longitudinal data in practice is powerful and has the ability to transform how schools support each student and we are proud to help make this happen. 

We are ready to scale globally after a number of documented successes in Chile. Mend the Gap is based in Pittsburgh and we are committed to making a difference here at home. With a product that's ready to use in schools across the world, we are eager to start getting feedback from our local community and start closing the achievement gap.

Big Data and Education
The increase of technologies, social networks and connectivity in general, has brought a big change in communications. For every minute that goes by, more than 200 million e-mails are sent to the world, 48 hours of video are uploaded to YouTube, more than 6,000 photographs are uploaded to Instagram, more than 560 websites are created, etc. Schools are not immune to the is phenomenon. How many notes, attendance records or annotations in a grade book are generated in a school per week? What applications can Big Data have in the field of education whether in the classroom, with administration, or at home? Imagine the advantages of being able to visualize and cross information about grades, attendance, risk of failure, gender gaps and more. What decisions or measures do you think a teacher can take when she notices that every time a certain student is missing, it is Monday? What if a UTP (academic coordinator) noticed the great gender gap in a subject taught by a certain teacher? The management and analysis of data can help detect early cases for attendance, low grades, even cases of abuse or bullying. Data visualizations allow us to have a broader and clearer picture of what is happening in a school, and analyzing that data allows us to make better and more informed decisions. Rodrigo Herrera (2018) published in a column in the newspaper La Tercera: "The application of intelligence in Big Data has already been implemented in some initiatives, such as measuring from the assistance and student performance in real time, allowing a virtual counselor to guide the person on what subjects should be reinforced, in addition to better organize their study times. (...) We are not only witnessing the fourth industrial revolution, but also the next step towards education for the future. " Sources: Munesh, K. & Pooja, M. (2014) Big data: a Review.

5 keys to combat chronic school absenteeism
Chronic early absenteeism is defined as missing more than 10% of the days of the school year, that is, having an attendance below 90%, which can have a severe impact in the future. Learn how the Ramón Barros Luco Industrial High School tackled this problem and achieved the highest average attendance of the schools in our platform, with 95.2%. The chronic absenteeism (have an attendance less than 90% ) can have very negative consequences on student performance is a problem that should not be taken lightly. The results of a study conducted in Chile by the Oportunidad Foundation show that in pre-school, more than 66% of students suffer from chronic absenteeism . He says: " The main effects of absenteeism in early childhood, are associated with worse results in mathematics and language in 1st and 5th grade, but also with problems of self-esteem and socialization , which can also be related to long-term effects, such as school dropout and failure academic, among others . "(Fundación Oportunidad, 2015). We went to see the case of the Ramón Barros Luco Industrial Liceo , where in 2017 there were 130 cases of chronic absenteeism. Although the average total attendance of the high school was 92%, looking more closely, they realized that there were many students who had less than 85% attendance (minimum required by the Ministry of Education). We were received by their director Iris del Carmen Verdugo , who after reading the study of the Oportunidad Foundation took it as a personal task to improve attendance at the school. We talked with her to find out how they managed to improve attendance with such good results. 1. Value student attendance The first thing Iris emphasizes, is to create a culture around the importance of student participation, so that both teachers and students understand the negative impact of missing classes. In the short term, the absence brings problems of socialization to the students. Students fall behind and are unsure of how to get caught up or are overwhelmed by the amount of work required. 2. Be consistent The second key to handling assistance according to Iris, is perseverance. "We have been very consistent with the issue of assistance, it is not an isolated activity . Monthly, or sometimes every 15 days , we review the evolution of the figures." The director highlighted that when reviewing Kimche's reports, he immediately realized where the problem was because they are very visual. For example, he noticed that the IVºA had a notoriously lower attendance on Tuesdays. When investigating what happened on Tuesdays that caused this rise in non-attendance, he was able to detect a problem that there was at the course level with a particular group of students who were struggling in that particular course. In another situation, he noticed that the IºA was missing a lot on Thursdays. It turned out that it was an academically very "heavy" day for particular students, so they considered ways to restructure the schedule to better support student needs. 3. Highlight the positive Third important factor according to Iris, is not only to focus on students with low attendance, but also to highlight and congratulate the students with good attendance (over 97% is considered outstanding). At the anniversary ceremony of the Ramón Barros Luco Industrial Liceo, with the representatives present, they awarded a diploma to all students with 100% attendance , which was more than 150 (out of a total of 760 students). On another occasion they sent a letter to all students with outstanding assistance, where they recognized them for their responsibility, dedication and commitment, and their families for providing the necessary support. 4. Communication Fourth, communication is very important . "We asked for the help of the chief teachers, who in their weekly hour of attention of parents focused on calling the parents of these missing children", said Iris. As stated before, it is good to communicate both with the parents of the students with outstanding attendance and with those who are at risk of repeating due to absence or who present chronic absenteeism. 5. Set concrete goals Finally, a factor that determined the high percentage of attendance of Liceo Industrial Barros Luco, was to set specific goals both at school level and per student . Having an attendance of 92%, they proposed to raise it to 94%, and achieved 95.2% . This was achieved through letters of commitment to the students, which established that although the Ministry requests a minimum 85%, missing more than 10% of the school year already involved a risk in several ways, so that students they had to commit to meet at least 92% attendance. "The most important thing is to create for these children a culture of assistance , which we clearly have as a mission. We are preparing them to go to the world of work , it is a very good practice that they understand now that assistance does matter , in school and at work . It is a culture that has to be developed, that will impact for good throughout its life ". Many thanks to Iris del Carmen Verdugo for their advice, and congratulations to the Liceo Industrial Ramón Barros Luco for their excellent results in attendance.
How does Chile measure school retention?
Little known are the numbers of school dropouts in Chile, their impacts and associated risk factors. According to ECLAC data, in Chile, 10% of high school students drop out of the education system, the figure being more intense in difficult contexts, in which 8 out of 10 cases correspond to students in poverty. As indicated by MINEDUC figures, school dropouts are higher for the first two socioeconomic quintiles and in secondary education, specifically in I and III. Fig 1. Incidence rate of school dropout by grade Source: Corporación Option based on MINEDUC statistics . The risk factors (or early warning) associated with dropping out are key when understanding the problem, according to the Technical Guidance document School Retention Plan Middle School Level developed by MINEDUC, these correspond to: Low average grades and student performance Low attendance to classes 2 or more course repetitions Discipline problemsSecond language students Mothers or teenage parents who continue to attend regular school. In the same way, other associated risk factors correspond to: Consumption of drugs and alcohol by children and young school system dropouts Consumption of drugs in the student 's immediate environment The quality agency , since the emergence of the SAC (Quality Assurance System) law, included the dimension of school retention as part of a more comprehensive vision of quality in education. As indicated by the agency, the indicator assesses the capacity of an educational establishment to achieve the permanence of its students in the formal education system. The spirit behind the measurement is that students remain in the formal educational system so that they acquire the knowledge, skills and attitudes expected to be developed during their school years.

School Attendance Results
The school attendance , as we have discussed in other columns , is key for those students develop the knowledge , skills and attitudes that are expected to learn during their education. It also contributes to their socio-emotional development and promotes fundamental habits for the future life of children and young people, such as responsibility. The attendance of the students on the other hand is linked to the school subsidy , the state provides resources to the schools by attended day, making variable the main source of income of the establishments. This is the double impact of this indicator , both in terms of learning and resources for the school. This is why it is important for the school to understand how the assistance behaves during the year in order to carry out better management. In this opportunity, we studied the data of Kimche (30,000 students in 42 schools with public funding) to give you an overview of the impact of the days of the week on student attendance .  With an average attendance of 90.5% in the schools of Kimche (considered "normal" by the quality agency), we find that in the decomposition it is Friday the day that students attend least with 89% .After identifying the most critical day, we went to study how the attendance of Friday is composed according to different variables, we will start with type of education. From the analysis it is found that both pre-school and professional technical education are those that have the most absence with 87% and 86% respectively. When we double-click on the most critical case for children, we found that on Friday the first media were the most needed, with 88% average attendance , already considered "repeated non-attendance" by the quality agency. Assistance on Fridays for courses for TP media niños We now return to Friday and break it down by other variables, for example by socioeconomic level, according to the SEP category, priority students, preferred and not receiving SEP subsidy. What happens is counterintuitive, usually tends to think that the category assigned by the SEP impacts on school attendance and the truth is that compared to the other groups it is not, both priority and preferential have similar assistance on Fridays .Another interesting comparison is by gender, distinguishing attendance on Fridays between men and women. The reality is that girls are the ones who come on Fridays compared to men , surpassing them in 1 pt. In any case the attendance of both Fridays is under 90% which is not considered within the acceptable levels. Finally, we are going to decompose according to the general average section. The students are grouped with average 6 to 7, 5 to 6, 4 to 5, etc. and intersect with attendance percentages on Fridays. In this case we can observe a clear relationship between the general average and attendance, while a student has a better performance, the data shows that he attends school more on Fridays .  These are some keys to face the phenomenon of school attendance, the important thing is always to start with the general data and decompose them until you reach the cause of the indicator. From then on what remains are the remedial, the school must take actions in this identified group first interpreting the data with qualitative information collected in the field and then designing improvements to increase the indicator over time.
